It carries 8 KB of OTP program memory, 256 x 8 RAM, and 256 x 8 EEPROM — enough for fixed-function control loops in motor drives, industrial timers, and appliance controllers where firmware is locked at the factory. On-chip peripherals include a PWM generator, watchdog timer, SCI serial interface, and an 8-channel 8-bit A/D converter. The 27 I/O lines route through a 40-pin PDIP package, rated for -40°C to 105°C operation on a 4.5 V to 5.5 V supply. Program memory is one-time programmable (OTP), meaning the firmware image is burned during production and cannot be changed afterward. This suits high-volume, fixed-function products where the code is mature and field updates are not required. For development or low-volume runs, plan for a separate UV-erasable windowed package or an emulator — the TMS370C742ANT itself is a production-only ordering code. ## Through-hole PDIP — design-in constraints The 40-pin PDIP (0.600\" body width) is a through-hole package. It fits standard DIP sockets and wave-solder processes. Rated for -40°C to 105°C, the TMS370C742ANT covers industrial and automotive under-hood temperature ranges. The 5 V supply rail (4.5 V to 5.5 V) is standard for legacy 5 V logic families and sensor interfaces. The SCI serial port runs at the core clock rate; no external oscillator is needed thanks to the internal oscillator. The part is RoHS non-compliant, which may affect shipments to regions with RoHS restrictions — confirm your local compliance requirements before ordering.","metaTitle":"TMS370C742ANT Texas Instruments 8-bit MCU, 5 MHz, 8 KB OTP","metaDescription":"Texas Instruments TMS370C742ANT 8-bit MCU, 5 MHz core, 8 KB OTP program memory, 256 x 8 RAM, 256 x 8 EEPROM, 27 I/O, SCI, PWM, WDT, 8-ch 8-bit ADC, -40 to","metaKeywords":null},"attributes":{"series":"TMS370","packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"5MHz","Series":"TMS370","Package":"Bulk","RAM Size":"256 x 8","Core Size":"8-Bit","EEPROM Size":"256 x 8","Peripherals":"PWM, WDT","Connectivity":"SCI","Mounting Type":"Through Hole","Number of I/O":"27","Core Processor":"TMS370","Package / Case":"40-DIP (0.600\\\", 15.24mm)","Data Converters":"A/D 8x8b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"8KB (8K x 8)","Program Memory Type":"OTP","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"40-PDIP","Voltage - Supply (Vcc/Vdd)":"4.5V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.4","stockQuantity":0,"priceTiers":[{"qty":32,"price":"$9.40000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/81ced0291e4d849186b769cd13e7fa5b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How many I/Os does TMS370C742ANT have?","answer":"27 I/O lines are available."},{"question":"How to program TMS370C742ANT?","answer":"Programming requires a compatible OTP programmer that supports the TMS370 family.
