Features

The R8C/34K Group of single-chip MCUs incorporates the R8C CPU core, employing sophisticated instructions

for a high level of efficiency. With 1 Mbyte of address space, and it is capable of executing instructions at high

speed. In addition, the CPU core boasts a multiplier for high-speed operation processing.

Power consumption is low, and the supported operating modes allow additional power control. These MCUs are

designed to maximize EMI/EMS performance.

Integration of many peripheral functions, including multifunction timer and serial interface, reduces the number of

system components.

The R8C/34K Group has data flash (1 KB × 4 blocks) with the background operation (BGO) function.

2. Central Processing Unit (CPU)

2.1

Data Registers (R0, R1, R2, and R3)

R0 is a 16-bit register for transfer, arithmetic, and logic operations. The same applies to R1 to R3. R0 can be split

into high-order bits (R0H) and low-order bits (R0L) to be used separately as 8-bit data registers. R1H and R1L are

analogous to R0H and R0L. R2 can be combined with R0 and used as a 32-bit data register (R2R0). R3R1 is

analogous to R2R0.

2.2

Address Registers (A0 and A1)

A0 is a 16-bit register for address register indirect addressing and address register relative addressing. It is also

used for transfer, arithmetic, and logic operations. A1 is analogous to A0. A1 can be combined with A0 and as a 32-

bit address register (A1A0).

2.3

Frame Base Register (FB)

FB is a 16-bit register for FB relative addressing.

2.4

Interrupt Table Register (INTB)

INTB is a 20-bit register that indicates the starting address of an interrupt vector table.

2.5

Program Counter (PC)

PC is 20 bits wide and indicates the address of the next instruction to be executed.

2.6

User Stack Pointer (USP) and Interrupt Stack Pointer (ISP)

The stack pointers (SP), USP and ISP, are each 16 bits wide. The U flag of FLG is used to switch between

USP and ISP.

2.7

Static Base Register (SB)

SB is a 16-bit register for SB relative addressing.

2.8

Flag Register (FLG)

FLG is an 11-bit register indicating the CPU state.

2.8.1

Carry Flag (C)

The C flag retains carry, borrow, or shift-out bits that have been generated by the arithmetic and logic unit.

2.8.2

Debug Flag (D)

The D flag is for debugging only. Set it to 0.

2.8.3

Zero Flag (Z)

The Z flag is set to 1 when an arithmetic operation results in 0; otherwise to 0.

2.8.4

Sign Flag (S)

The S flag is set to 1 when an arithmetic operation results in a negative value; otherwise to 0.

2.8.5

Register Bank Select Flag (B)

Register bank 0 is selected when the B flag is 0. Register bank 1 is selected when this flag is set to 1.

2.8.6

Overflow Flag (O)

The O flag is set to 1 when an operation results in an overflow; otherwise to 0.

The U flag is set to 0 when a hardware interrupt request is acknowledged or the INT instruction of software

interrupt numbers 0 to 31 is executed.

2.8.9

Processor Interrupt Priority Level (IPL)

IPL is 3 bits wide and assigns processor interrupt priority levels from level 0 to level 7.

If a requested interrupt has higher priority than IPL, the interrupt is enabled.

2.8.10 Reserved Bit

If necessary, set to 0. When read, the content is undefined.

R8C/34K Group

Figure 3.1 is a Memory Map of R8C/34K Group. The R8C/34K Group has a 1-Mbyte address space from addresses

00000h to FFFFFh. The internal ROM (program ROM) is allocated lower addresses, beginning with address

0FFFFh. A 64-Kbyte internal ROM area is allocated addresses 04000h to 13FFFh.

The fixed interrupt vector table is allocated addresses 0FFDCh to 0FFFFh. The starting address of each interrupt

routine is stored here.

The internal ROM (data flash) is allocated addresses 03000h to 03FFFh.

The internal RAM is allocated higher addresses, beginning with address 00400h. For example, a 8-Kbyte internal

RAM area is allocated addresses 00400h to 023FFh. The internal RAM is used not only for data storage but also as

a stack area when a subroutine is called or when an interrupt request is acknowledged.

Special function registers (SFRs) are allocated addresses 00000h to 002FFh and 02C00h to 02FFFh (the SFR areas

for the DTC and other modules). Peripheral function control registers are allocated here. All unallocated spaces

within the SFRs are reserved and cannot be accessed by users.

Notes:

1. VCC = 2.7 to 5.5 V and Topr = 0 to 60 °C, unless otherwise specified.

2. Definition of programming/erasure endurance

The programming and erasure endurance is defined on a per-block basis.

If the programming and erasure endurance is n (n = 1,000), each block can be erased n times. For example, if 1,024 1-byte

writes are performed to different addresses in block A, a 1 Kbyte block, and then the block is erased, the

programming/erasure endurance still stands at one. However, the same address must not be programmed more than once

per erase operation (overwriting prohibited).

3. Endurance to guarantee all electrical characteristics after program and erase. (1 to Min. value can be guaranteed.)

4. In a system that executes multiple programming operations, the actual erasure count can be reduced by writing to sequential

addresses in turn so that as much of the block as possible is used up before performing an erase operation. For example,

when programming groups of 16 bytes, the effective number of rewrites can be minimized by programming up to 128 groups

before erasing them all in one operation. It is also advisable to retain data on the erasure endurance of each block and limit

the number of erase operations to a certain number.

5. If an error occurs during block erase, attempt to execute the clear status register command, then execute the block erase

command at least three times until the erase error does not occur.

6. Customers desiring program/erase failure rate information should contact their Renesas technical support representative.

7. The data hold time includes time that the power supply is off or the clock is not supplied.

reduce the actual erasure endurance. It is also advisable to retain data on the erasure endurance of each block and limit the

General Precautions in the Handling of MPU/MCU Products

The following usage notes are applicable to all MPU/MCU products from Renesas. For detailed usage notes

on the products covered by this manual, refer to the relevant sections of the manual. If the descriptions under

General Precautions in the Handling of MPU/MCU Products and in the body of the manual differ from each

other, the description in the body of the manual takes precedence.

1. Handling of Unused Pins

Handle unused pins in accord with the directions given under Handling of Unused Pins in the

manual.

 The input pins of CMOS products are generally in the high-impedance state. In operation

with an unused pin in the open-circuit state, extra electromagnetic noise is induced in the

vicinity of LSI, an associated shoot-through current flows internally, and malfunctions occur

due to the false recognition of the pin state as an input signal become possible. Unused

pins should be handled as described under Handling of Unused Pins in the manual.

2. Processing at Power-on

The state of the product is undefined at the moment when power is supplied.

 The states of internal circuits in the LSI are indeterminate and the states of register

settings and pins are undefined at the moment when power is supplied.

In a finished product where the reset signal is applied to the external reset pin, the states

of pins are not guaranteed from the moment when power is supplied until the reset

process is completed.

In a similar way, the states of pins in a product that is reset by an on-chip power-on reset

function are not guaranteed from the moment when power is supplied until the power

reaches the level at which resetting has been specified.

3. Prohibition of Access to Reserved Addresses

Access to reserved addresses is prohibited.

 The reserved addresses are provided for the possible future expansion of functions. Do

not access these addresses; the correct operation of LSI is not guaranteed if they are

accessed.

4. Clock Signals

After applying a reset, only release the reset line after the operating clock signal has become

stable. When switching the clock signal during program execution, wait until the target clock

signal has stabilized.

 When the clock signal is generated with an external resonator (or from an external

oscillator) during a reset, ensure that the reset line is only released after full stabilization of

the clock signal. Moreover, when switching to a clock signal produced with an external

resonator (or by an external oscillator) while program execution is in progress, wait until

the target clock signal is stable.

5. Differences between Products

Before changing from one product to another, i.e. to one with a different part number, confirm

that the change will not lead to problems.

 The characteristics of MPU/MCU in the same group but having different part numbers may

differ because of the differences in internal memory capacity and layout pattern. When

changing to products of different part numbers, implement a system-evaluation test for

each of the products.

which it is not intended without the prior written consent of Renesas Electronics. Renesas Electronics shall not be in any way liable for any damages or losses incurred by you or third parties arising from the

use of any Renesas Electronics product for an application categorized as "Specific" or for which the product is not intended where you have failed to obtain the prior written consent of Renesas Electronics.

The quality grade of each Renesas Electronics product is "Standard" unless otherwise expressly specified in a Renesas Electronics data sheets or data books, etc.

"Standard":

Computers; office equipment; communications equipment; test and measurement equipment; audio and visual equipment; home electronic appliances; machine tools;

personal electronic equipment; and industrial robots.

"High Quality": Transportation equipment (automobiles, trains, ships, etc.); traffic control systems; anti-disaster systems; anti-crime systems; safety equipment; and medical equipment not specifically

designed for life support.

"Specific":

Aircraft; aerospace equipment; submersible repeaters; nuclear reactor control systems; medical equipment or systems for life support (e.g. artificial life support devices or systems), surgical

implantations, or healthcare intervention (e.g. excision, etc.), and any other applications or purposes that pose a direct threat to human life.
