The Texas Instruments TMS27PC400-12NL is a 4 Mbit (256K x 16) CMOS One-Time Programmable (OTP) Read-Only Memory (ROM). This asynchronous device offers a maximum access time of 120ns, facilitating efficient data retrieval. Its memory organization provides 262,144 words, each 16 bits wide. The component operates from a supply voltage range of 4.5V to 5.5V, with a nominal voltage of 5V, and features a standby current of 0.1mA and a maximum supply current of 50mA.
The TMS27PC400-12NL is housed in a 40-pin Plastic Dual In-line Package (PDIP) with through-hole mounting, a standard for many legacy and industrial applications. Its 3-state outputs allow for bus-sharing configurations. This memory component finds application in systems requiring non-volatile program storage, such as industrial control, telecommunications infrastructure, and legacy computing systems. The operating temperature range is 0°C to 70°C.
