GENERAL DESCRIPTION

The SMJ27C010A series are 131072 by 8-bit (1048576-

bit), ultaviolet (UV) light erasable, electrically programmable

read-only memories (EPROMs).

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 SMJ27C010A EPROM is offered in a ceramic

dual-in-line package (J suffix) designed for insertion in

mounting-hole rows on 15.2mm (600mil) centers.

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 algorithm. The SNAP! Pulse programming

algorithm uses a V

PP

of 13V and a V

CC

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.
