This is a part you program once and commit to production. The 64-pin DIP package with through-hole mounting suits legacy sockets, prototyping boards, and environments where a soldered QFP is less practical. ## Peripherals and I/O — what the 44 pins buy you 44 I/O lines give this part enough headroom for a keypad matrix, a small character LCD, and a handful of sensor interrupts without an external port expander. The integrated peripherals include SCI and SPI serial interfaces for communicating with a host controller or a serial EEPROM, plus PWM outputs and a watchdog timer. The 8-channel, 8-bit ADC handles analog inputs like potentiometer position or thermistor voltage directly. The 4.5 V supply rail is a single-supply design, simplifying the power tree in a 5 V system. ## Lifecycle and sourcing posture That said, OTP MCUs are a shrinking category — fabs retool for Flash and mask-ROM lines, and the TMS370 architecture is decades old. For a production BOM that depends on this exact order code, the prudent move is to qualify the part into the bill of materials now and keep a sourcing channel open.","metaTitle":"Texas Instruments TMS370C756ANMT 8-bit OTP MCU, 5 MHz, 16 KB","metaDescription":"Texas Instruments TMS370C756ANMT 8-bit TMS370 MCU with 16 KB OTP, 5 MHz, 44 I/O, SCI/SPI, 8x8b ADC, -40°C to 105°C.
