The STMicroelectronics ST10F276Z5T3 is a 16-bit microcontroller with a MAC unit, running a 16-bit data bus at a maximum frequency of 40M Hz. It integrates 512kB of flash memory and 68kB of RAM on chip, and exposes CAN, EBI/EMI, I2C, UART and USART interfaces alongside 24 ADC channels, five timers/counters and POR, PWM and WDT peripherals. The ST10F276Z5T3 is supplied in a 144-pin surface-mount LQFP measuring 20.2mm by 20.2mm with a 1.45mm height, and operates from a 4.5V to 5.5V supply over a -40 to 125 degrees C range. STMicroelectronics lists the device with an NRND lifecycle status.

The ST10F276Z5T3 targets embedded control applications that need deterministic 16-bit processing together with on-chip non-volatile storage, and its CAN interface and 125 degrees C maximum operating temperature make it well suited to automotive body and powertrain modules, industrial drives and factory automation controllers. The 24 ADC channels and PWM support let a single device close analog sensing and motor or actuator control loops without external converters, while the EBI/EMI bus allows expansion where 512kB of internal flash is not enough. Buyers are typically automotive tier-one suppliers and industrial equipment OEMs sustaining long-life platforms. Because STMicroelectronics has placed the part at NRND, sourcing teams commonly buy it for maintenance and last-time-build of existing designs rather than for new programs.
