description

The TMS27C210A series are 65 536 by 16-bit (1 048 576-bit), ultraviolet-light erasable, electrically

programmable read-only memories (EPROMs).

The TMS27PC210A series are 65 536 by 16-bit (1 048 576-bit), one-time programmable (OTP) electrically

programmable read-only memories (PROMs).

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 74 TTL circuits

without the use of external pullup resistors. Each output can drive one Series 74 TTL circuit without external

resistors.

The TMS27C210A EPROM is offered in a dual-in-line ceramic package (J suffix) designed for insertion in

mounting hole rows on 15,2-mm (600-mil) centers. The TMS27C210A is offered with two choices of

temperature ranges, 0

°C to 70°C (JL suffix) and − 40°C to 85°C (JE suffix). See Table 1.

The TMS27PC210A OTP PROM is offered in a 44-pin plastic leaded chip carrier package using 1,25-mm

(50-mil) lead spacing ( FN suffix). The TMS27PC210A is offered with two choices of temperature ranges,

0

°C to 70°C (FNL suffix) and −40°C to 85°C (FNE suffix). See Table 1.

These EPROMs and OTP PROMs operate from a single 5-V supply ( in the read mode), they are ideal for use

in microprocessor based systems. One other (13 V) supply is needed for programming. All programming signals

are TTL level. For programming outside the system, existing EPROM programmers can be used.
