The Microchip Technology Inc. 25AA320/25LC320/

25C320 (25XX320^*) are 32 Kbit serial Electrically

Erasable PROMs. The memory is accessed via a

simple Serial Peripheral Interface (SPI) compatible

serial bus. The bus signals required are a clock input

(SCK) plus separate data in (SI) and data out (SO)

lines. Access to the device is controlled through a Chip

Select (CS) input.

Supply Voltage

The WP pin function is blocked when the WPEN bit in

the STATUS register is low. This allows the user to

install the 25XX320 in a system with WP pin grounded

and still be able to write to the STATUS register. The

WP pin functions will be enabled when the WPEN bit is

set high.

2.1

Chip Select (CS)

A low level on this pin selects the device. A high level

deselects the device and forces it into Standby mode.

However, a programming cycle which is already

initiated or in progress will be completed, regardless of

the CS input signal. If CS is brought high during a

program cycle, the device will go into Standby mode as

soon as the programming cycle is complete. When the

device is deselected, SO goes to the high-impedance

state, allowing multiple parts to share the same SPI

bus. A low-to-high transition on CS after a valid write

sequence initiates an internal write cycle. After power-

up, a low level on CS is required prior to any sequence

being initiated.

2.4

Serial Input (SI)

The SI pin is used to transfer data into the device. It

receives instructions, addresses, and data. Data is

latched on the rising edge of the serial clock.

2.5

Serial Clock (SCK)

The SCK is used to synchronize the communication

between a master and the 25XX320. Instructions,

addresses, or data present on the SI pin are latched on

the rising edge of the clock input, while data on the SO

pin is updated after the falling edge of the clock input.

2.2

Serial Output (SO)

The SO pin is used to transfer data out of the 25XX320.

During a read cycle, data is shifted out on this pin after

the falling edge of the serial clock.

2.6

Hold (HOLD)

The HOLD pin is used to suspend transmission to the

25XX320 while in the middle of a serial sequence with-

out having to re-transmit the entire sequence again. It

must be held high any time this function is not being

used. Once the device is selected and a serial

sequence is underway, the HOLD pin may be pulled

low to pause further serial communication without

resetting the serial sequence. The HOLD pin must be

brought low while SCK is low, otherwise the HOLD

function will not be invoked until the next SCK high-to-

low transition. The 25XX320 must remain selected dur-

ing this sequence. The SI, SCK, and SO pins are in a

high-impedance state during the time the device is

paused and transitions on these pins will be ignored. To

resume serial communication, HOLD must be brought

high while the SCK pin is low, otherwise serial

communication will not resume. Lowering the HOLD

line at any time will tri-state the SO line.

2.3

Write-Protect (WP)

This pin is used in conjunction with the WPEN bit in the

STATUS register to prohibit writes to the nonvolatile

bits in the STATUS register. When WP is low and

WPEN is high, writing to the nonvolatile bits in the STA-

TUS register is disabled. All other operations function

normally. When WP is high, all functions, including

writes to the nonvolatile bits in the STATUS register

operate normally. If the WPEN bit is set, WP low during

a STATUS register write sequence will disable writing

to the STATUS register. If an internal write cycle has

already begun, WP going low will have no effect on the

write.

3.3

Write Sequence

3.0

FUNCTIONAL DESCRIPTION

Prior to any attempt to write data to the 25XX320, the

write enable latch must be set by issuing the WREN

instruction (Figure 3-4). This is done by setting CS low

and then clocking out the proper instruction into the

25XX320. After all eight bits of the instruction are

transmitted, the CS must be brought high to set the

write enable latch. If the write operation is initiated

immediately after the WREN instruction without CS

being brought high, the data will not be written to the

array because the write enable latch will not have been

properly set.

3.1

Principles Of Operation

The 25XX320 are 4096 byte Serial EEPROMs

designed to interface directly with the Serial Peripheral

Interface (SPI) port of many of today’s popular

microcontroller

families,

including

Microchip’s

PIC16C6X/7X microcontrollers. It may also interface

with microcontrollers that do not have a built-in SPI port

by using discrete I/O lines programmed properly with

the software.

The 25XX320 contains an 8-bit instruction register. The

device is accessed via the SI pin, with data being

clocked in on the rising edge of SCK. The CS pin must

be low and the HOLD pin must be high for the entire

operation.

Once the write enable latch is set, the user may

proceed by setting the CS low, issuing a WRITE

instruction, followed by the 16-bit address, with the four

MSBs of the address being “don’t care” bits, and then

the data to be written. Up to 32 bytes of data can be

sent to the 25XX320 before a write cycle is necessary.

The only restriction is that all of the bytes must reside

in the same page. A page address begins with xxxx

xxxx xxx0 0000and ends with xxxx xxxx xxx1

1111. If the internal address counter reaches xxxx

xxxx xxx1 1111and the clock continues, the counter

will roll back to the first address of the page and over-

write any data in the page that may have been written.

Table 3-1 contains a list of the possible instruction

bytes and format for device operation. All instructions,

addresses and data are transferred MSB first, LSB last.

Data is sampled on the first rising edge of SCK after CS

goes low. If the clock line is shared with other

peripheral devices on the SPI bus, the user can assert

the HOLD input and place the 25XX320 in ‘HOLD’

mode. After releasing the HOLD pin, operation will

resume from the point when the HOLD was asserted.

For the data to be actually written to the array, the CS

must be brought high after the Least Significant bit (D0)

of the n^thdata byte has been clocked in. If CS is

brought high at any other time, the write operation will

not be completed. Refer to Figure 3-2 and Figure 3-3

for more detailed illustrations on the byte write

sequence and the page write sequence, respectively.

While the write is in progress, the STATUS register may

be read to check the status of the WPEN, WIP, WEL,

BP1 and BP0 bits (Figure 3-6). A read attempt of a

memory array location will not be possible during a

write cycle. When the write cycle is completed, the

write enable latch is reset.

3.2

Read Sequence

The device is selected by pulling CS low. The 8-bit

READ instruction is transmitted to the 25XX320 fol-

lowed by the 16-bit address, with the four MSBs of the

address being “don’t care” bits. After the correct READ

instruction and address are sent, the data stored in the

memory at the selected address is shifted out on the

SO pin. The data stored in the memory at the next

address can be read sequentially by continuing to pro-

vide clock pulses. The internal Address Pointer is auto-

matically incremented to the next higher address after

each byte of data is shifted out. When the highest

address is reached (0FFFh), the address counter rolls

over to address 0000h allowing the read cycle to be

continued indefinitely. The read operation is terminated

by raising the CS pin (Figure 3-1).

The Write Enable Latch (WEL) bit indicates the status

of the write enable latch. When set to a ‘1’, the latch

allows writes to the array, when set to a ‘0’, the latch

prohibits writes to the array. The state of this bit can

always be updated via the WREN or WRDI commands

regardless of the state of write protection on the STA-

TUS register. This bit is read-only.

3.5

Read Status Register Instruction

(RDSR)

The Read Status Register instruction (RDSR) provides

access to the STATUS register. The STATUS register

may be read at any time, even during a write cycle. The

STATUS register is formatted as follows:

The Block Protection (BP0 and BP1) bits indicate

which blocks are currently write-protected. These bits

are set by the user issuing the WRSRinstruction. These

bits are nonvolatile.

When the chip is hardware write-protected, only writes

Write Status Register Instruction

(WRSR)

to nonvolatile bits in the STATUS register are disabled.

See Table 3-3 for a matrix of functionality on the WPEN

bit.

The Write Status Register instruction (WRSR) allows the

user to select one of four levels of protection for the

array by writing to the appropriate bits in the STATUS

register. The array is divided up into four segments.

The user has the ability to write-protect none, one, two,

or all four of the segments of the array. The partitioning

is controlled as shown in Table 3-2.

See Figure 3-7 for the WRSR timing sequence.

Write-Protected

The Write-Protect Enable (WPEN) bit is a nonvolatile

bit that is available as an enable bit for the WP pin. The

Write-Protect (WP) pin and the Write-Protect Enable

(WPEN) bit in the STATUS register control the pro-

grammable hardware write-protect feature. Hardware

write protection is enabled when WP pin is low and the

WPEN bit is high. Hardware write protection is disabled

when either the WP pin is high or the WPEN bit is low.

Power-On State

The following protection has been implemented to

prevent inadvertent writes to the array:

The 25XX320 powers on in the following state:

• The device is in low-power Standby mode

• The write enable latch is reset on power-up

(CS= 1)

• A WRITE ENABLEinstruction must be issued to

• The write enable latch is reset

set the write enable latch

• SO is in high-impedance state

• After a byte write, page write or STATUS register

write, the write enable latch is reset

• A low level on CS is required to enter active state

• CS must be set high after the proper number of

clock cycles to start an internal write cycle

• Access to the array during an internal write cycle

is ignored and programming is continued

NOTES:

DS21227F-page 24

Note the following details of the code protection feature on Microchip devices:

•

Microchip products meet the specification contained in their particular Microchip Data Sheet.

•

Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the

intended manner and under normal conditions.

•

There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our

knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data

Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

•

Microchip is willing to work with the customer who is concerned about the integrity of their code.

Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not

mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our

products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts

allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

Information contained in this publication regarding device

applications and the like is provided only for your convenience

and may be superseded by updates. It is your responsibility to

ensure that your application meets with your specifications.

MICROCHIP MAKES NO REPRESENTATIONS OR

WARRANTIES OF ANY KIND WHETHER EXPRESS OR

IMPLIED, WRITTEN OR ORAL, STATUTORY OR

OTHERWISE, RELATED TO THE INFORMATION,

INCLUDING BUT NOT LIMITED TO ITS CONDITION,

QUALITY, PERFORMANCE, MERCHANTABILITY OR

FITNESS FOR PURPOSE. Microchip disclaims all liability

arising from this information and its use. Use of Microchip

devices in life support and/or safety applications is entirely at

the buyer’s risk, and the buyer agrees to defend, indemnify and

hold harmless Microchip from any and all damages, claims,

suits, or expenses resulting from such use. No licenses are
