It integrates an 8-channel 10-bit ADC, PWM and watchdog timer peripherals, plus a serial I/O interface — a single-chip control solution for motor drives, industrial pumps, and power-conversion stages where firmware is factory-locked and never field-updated. ## OTP memory — no field updates possible The 16 KB OTP (one-time programmable) memory means the firmware mask is burned during production and cannot be changed afterward. This is the defining BOM constraint: every firmware revision requires a new mask and a new device order code. If your design needs field-reprogrammability or iterative firmware tuning, the ROMless TN80C196KC20 paired with external Flash is the alternative — but that trades PCB area and BOM count for flexibility. ## 20 MHz core — what it means for the control loop The 20 MHz clock drives the MCS 96 pipeline. The integrated PWM and WDT peripherals handle a closed-loop control loop without external timers. ## Temperature grade and environment Rated 0°C to 70°C, this part is for indoor, conditioned environments. The supply range is 4.5 V to 5.5 V. ## Lifecycle and sourcing reality Listed as Active, so no formal last-time-buy has been issued. However, OTP mask variants like this one have finite production windows — the mask ROM process is specific to a fab line, and Intel (now part of the broader legacy portfolio) may not run it indefinitely. The 87C series is a mature 16-bit architecture; for production continuity, verify mask availability with your factory contact before freezing the BOM. The YW87C196KC20 is sourced and quoted to order through independent distribution, with availability and current pricing confirmed at quote time.","metaTitle":"Intel YW87C196KC20 16-bit MCU, 20MHz, 16KB OTP, 80-QFP","metaDescription":"Intel YW87C196KC20 16-bit MCS 96 MCU with 20MHz core, 16KB OTP program memory, 8x10b ADC, 40 I/O, 80-QFP.
