Product details
Overview
ST10F276-4TX3 from STMicroelectronics is a 16-bit microcontroller with integrated MAC unit, 512 KB Flash (32-bit fetch), 66 KB XRAM, and dual CAN 2.0B interfaces. It operates at up to 64 MHz (31.25 ns instruction cycle), supports 24-channel 10-bit ADC (3 µs conversion), and targets real-time industrial control systems requiring deterministic timing and fieldbus connectivity.
For engineers reviewing the ST10F276-4TX3 datasheet, ST10F276-4TX3 pinout, ST10F276-4TX3 application, or ST10F276-4TX3 equivalent, key selection criteria include its 16-level priority interrupt system (56 sources), programmable external bus with 5 chip-selects, dual CAN controllers with 64-message RAM, on-chip PLL (4–12 MHz input), and fail-safe features including oscillator watchdog and programmable WDT.
Technical Context
The ST10F276-4TX3 implements a high-performance 16-bit CPU with dedicated MAC coprocessor supporting 16×16-bit multiply and 40-bit accumulate in single cycle. Its memory architecture separates 512 KB on-chip Flash (32-bit wide) from 320 KB extension Flash (16-bit wide), enabling concurrent code/data access within a 16 MB linear address space.
Real-time operation is reinforced by an 8-channel peripheral event controller for zero-cycle interrupt-driven data transfer, two multi-functional timer units (5 timers total), dual 16-channel CAPCOM units, and 4+4-channel PWM/XPWM with dead-time insertion. The dual CAN modules support independent bus operation (C-CAN v2.0B) with configurable message objects and hardware acceptance filtering.

FAQ
What package options are available for ST10F276-4TX3?
The ST10F276-4TX3 is offered in both PQFP144 (28 × 28 × 3.4 mm) and LQFP144 (20 × 20 × 1.4 mm) packages, as confirmed in STMicroelectronics Doc ID 12303 Rev 4, Section 24. Both packages share identical pinout and electrical characteristics, differing only in mechanical dimensions and thermal profile.
Does ST10F276-4TX3 support in-system programming via CAN?
Yes - the device includes a standard CAN-based bootstrap loader (BSL) that allows firmware updates over CAN bus without JTAG. It supports configurable baud rates, message object filtering, and secure signature verification before loading new code, as detailed in Section 5.4 of the datasheet.
What is the minimum ADC conversion time and how is it achieved?
The minimum ADC conversion time is 3 µs, achieved using the internal 10-bit successive approximation register (SAR) architecture with dedicated sample-and-hold circuitry. This timing is guaranteed under recommended operating conditions (VDD = 5 V ±10%, TA = –40 to +85 °C) per Section 23.7.1 of the datasheet.
How does the MAC unit improve real-time control performance?
The MAC unit executes 16×16-bit multiplication and 40-bit accumulation in a single instruction cycle, eliminating software loop overhead for FIR filters, PID computations, and Clarke/Park transforms. This enables sub-microsecond control loop execution - critical for high-bandwidth motor control and power converter regulation.
