TMS27PC128 131 072-BIT PROGRAMMABLE READ-ONLY MEMORY
SMLS128E–OCTOBER 1984–REVISED JANUARY 1993
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 pull-up resistors. Each output can drive one Series 74 TTL circuit without external
resistors.
The data outputs are three-state for connecting multiple devices to a common bus. The TMS27C128 and the
TMS27PC128 are pin compatible with 28-pin 128K MOS ROMs, PROMs, and EPROMs.
The TMS27C128 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 TMS27C128 is offered with two operating temperature
ranges of 0°C to 70°C (JL suffix) and – 40°C to 85°C (JE suffix). The TMS27C128 is also offered with 168-hour
burn-in temperature ranges (JL4 and JE4 suffixes). (See table below).
The TMS27PC128 PROM is offered in a dual-in-line plastic package (N suffix) designed for insertion in mounting
hole rows on 15,2-mm (600-mil) centers. The TMS27PC128 is also supplied in a 32-lead plastic leaded chip
carrier package using 1,25-mm (50-mil) lead spacing (FM suffix). The TMS27PC128 is also offered with two
operating temperature ranges of 0°C to 70°C (NL and FML suffixes) and – 40°C to 85°C (NE and FME suffixes).
The TMS27PC128 is also offered with 168 hour burn-in temperature ranges (NL4, FML4, NE4, and FME4
suffixes). (See table below).
All package styles conform to JEDEC standards.

These EPROMs and PROMs operate from a single 5-V supply (in the read mode), thus are ideal for use in
microprocessor-based systems. One other 12-13-V supply is needed for programming . All programming
signals are TTL level. These devices are programmable by using the SNAP! Pulse programming algorithm.The
SNAP! Pulse programming algorithm uses a V_PP of 13.0 V and a V_CC of 6.5 V for a nominal programming time
of two seconds. For programming outside the system, existing EPROM programmers can be used. Locations
may be programmed singly, in blocks, or at random.
