It carries 8 KB of OTP program memory — one-time programmable, no field updates — plus 256 x 8 bytes each of RAM and EEPROM. On-chip peripherals include PWM, a watchdog timer, and an SPI interface, with 22 general-purpose I/O lines. The part is housed in a 40-pin DIP (0.600\" body, 15.24 mm pitch) and operates over the industrial temperature range of -40°C to 105°C. Typical applications include industrial control panels, motor drive logic, and embedded control in factory automation where firmware is locked at the factory and field reprogramming is not required. ## OTP memory: no field updates possible The 8 KB program memory is OTP — once programmed, the code is permanent. That means firmware must be fully validated before production burn. No field updates, no patches, no bootloader. ## Industrial temperature range and supply Rated for -40°C to 105°C ambient, this MCU operates on a 4.5 V to 5.5 V supply. ## Through-hole package — legacy board fit The 40-pin DIP (0.600\" body) is a through-hole package. That makes it a direct drop-in for existing boards designed for that footprint. ## Lifecycle and sourcing reality The TMS370C712ANT is listed as Active on the manufacturer's lifecycle record. It is RoHS non-compliant, so verify your assembly line's solder requirements if you are using lead-free processes.","metaTitle":"TI TMS370C712ANT MCU 8-bit 8KB OTP 5MHz 40-DIP","metaDescription":"Texas Instruments TMS370C712ANT 8-bit MCU, 8KB OTP, 256x8 RAM/EEPROM, 5MHz, 22 I/O, SPI, PWM, WDT, -40 to 105°C, 40-DIP.","metaKeywords":null},"attributes":{"series":"TMS370","packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"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":"SPI","Mounting Type":"Through Hole","Number of I/O":"22","Core Processor":"TMS370","Package / Case":"40-DIP (0.600\\\", 15.24mm)","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":"$9.22","stockQuantity":0,"priceTiers":[{"qty":33,"price":"$9.22000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/70d9c25c662893a05a0e29ebf4f2baf3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can I replace TMS370C712ANT with a flash-based MCU?","answer":"Yes, a flash-based MCU can replace it if the application requires field-reprogrammability. The TMS370 family includes flash variants, and the C2000 F280041PZQR is a 32-bit alternative with 100 MHz, 128 KB flash, and a wider peripheral set — but it is a different architecture (C28x) and requires a board redesign (surface-mount, different pinout).
