GENERAL DESCRIPTION
The SMJ27C010A series are 131072 by 8-bit (1048576-
bit), ultaviolet (UV) light erasable, electrically programmable
read-only memories (EPROMs).
These EPROMs operate from a single 5V supply (in the read
mode), and therefore, are ideal for use in microprocessor-based
systems. One other 13V supply is needed for programming.
All programming signals are TTL level. These devices are
programmable using the SNAP! Pulse programming algo-
These devices are fabricated using power-saving CMOS
technology for high speed and simple interface with MOS and
bipolar circuits. All inputs (including program data inputs) can
be driven by Series 54 TTL circuits without the use of external
pullup resistors. Each output can drive one Series 54 TTL
circuit without external resistors.
The SMJ27C010AEPROM is offered in a ceramic dual-in-
line package (J suffix) designed for insertion in mounting-hole
rows on 15.2mm (600mil) centers.
rithm. The SNAP! Pulse programming algorithm uses a VPP
of 13V and a VCC of 6.5V for a nominal programming time
of thirteen seconds. For programming outside the system,
existing EPROM programmers can be used. Locations can be
programmed singly, in blocks, or at random.

OPERATION
The seven modes of operation are listed in Table 1. The read mode requires a single 5V supply. All inputs are TTL level
except for VPP during programming (13V for SNAP! Pulse), and 12V on A9 for signature mode.

programming algorithm as illustrated by the flow chart (Figure
1). This algorithm programs in a nominal time of thirteen
seconds. Actual programming time varies as a function of the
programmer used.
READ/OUTPUT DISABLE
When the outputs of two or more SMJ27C010As are connected
in parallel on the same bus, the output of any particular device
in the circuit can be read with no interference from competing
outputs of the other devices. To read the output of a single
device, a low level signal is applied to the E\ and G\ pins. All
other devices in the circuit should have their outputs disabled
by applying a high-level signal to one of these pins.
The SNAP! Pulse programming algorithm uses an initial pulse
of 100 microseconds (μs) followed by a byte verification to
determine when the addressed byte has been successfully
programmed. Up to ten 100μs pulses per byte are provided
before a failure is recognized.
LATCHUP IMMUNITY
Latchup immunity on the SMJ27C010A is a minimum of
250mAon all inputs and outputs. This feature provides latchup
immunity beyond any potential transients at the printed circuit
board level when the devices are interfaced to industry-standard
TTL or MOS logic devices. The input/ output layout ap-
proach controls latchup without compromising performance
or packing density.
The programming mode is achieved when VPP = 13V, VCC
=
6.5V, E\ = VIL, and G\ = VIH. Data is presented in parallel
(eight bits) on pins DQ0 through DQ7. Once addresses and
data are stable, PGM\ is pulsed low.
More than one device can be programmed when the devices
are connected in parallel. Locations can be programmed in
any order. When the SNAP! Pulse programming routine is
POWER DOWN
complete, all bits are verified with VCC = VPP = 5V ± 10%.
Active ICC supply current can be reduced from 30mAto 500μA
by applying a high TTL input on E\ and to 100μA by applying
a high CMOS input on E\. In this mode all outputs are in the
high-impedance state.
PROGRAM INHIBIT
Programming can be inhibited by maintaining high level
inputs on the E\ or the PGM\ pins.
ERASURE
Before programming, the SMJ27C010A EPROM is erased by
exposing the chip through the transparent lid to a high- inten-
sity ultraviolet light (wavelength 2537 Å). The recommended
minimum exposure dose (UV intensity x exposure time) is 15-
PROGRAM VERIFY
Programmed bits can be verified with VPP = 13V when G\ =
VIL, and E\ = VIL, and PGM\ = VIH.
W.s/cm2. A typical 12-mW/cm2, filterless UV lamp erases the
device in 21 minutes. The lamp should be located about 2.5cm
above the chip during erasure. After erasure, all bits are in the
high state. It should be noted that normal ambient light contains
the correct wavelength for erasure; therefore, when using the
SMJ27C010A, the window should be covered with an opaque
label. After erasure (all bits in logic high state), logic lows are
programmed into the desired locations. A programmed low
can be erased only by ultraviolet light.
SIGNATURE MODE
The signature mode provides access to a binary code
identifying the manufacturer and type. This mode is activated
when A9 (pin 26) is forced to 12V. Two identifier bytes are
accessed by togglingA0. All other addresses must be held low.
The signature code for these devices is 97D6. A0 low selects
the manufacturer’s code 97 (Hex), and A0 high
device code D6 (Hex), as shown in Table 2.
