description

The TMS27C040 devices are 524288 by 8-bit (4194304-bit), ultraviolet (UV) light erasable, electrically programmable read-only memories (EPROMs).

The TMS27PC040 devices are 524288 by 8-bit (4194304-bit), one-time programmable (OTP) electrically programmable read-only memories (PROMs).

These devices are fabricated using CMOS technology for high speed and simple interface with MOS and bipolar circuits. All inputs (including program data inputs) can be driven by the Series 74 TTL circuits. Each output can drive one Series 74 TTL circuit without external resistors.

The data outputs are 3-state for connecting multiple devices to a common bus

The TMS27C040 is offered in a 600-mil ceramic dual-in-line package (J suffix). The TMS27C040 is offered with two choices of temperature ranges of 0°C to 70°C (JL suffix) and -40°C to 85°C (JE suffix). (See Table 1.)

The TMS27PC040 is offered in a 32-lead plastic leaded chip carrier package (FM suffix). The TMS27PC040 is offered with two choices of temperature ranges of 0°C to 70°C (JL suffix) and -40°C to 85°C (JE suffix).

These EPROMs and PROMS operate from a single 5-V supply (in the read mode), and 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.
