Product details
Overview
ST10F296TR from STMicroelectronics is a high-performance 16-bit microcontroller with integrated MAC unit, 832 Kbyte Flash memory (512 KB IFlash + 320 KB XFlash), 68 Kbyte RAM (2 KB IRAM + 66 KB XRAM), dual CAN 2.0B interfaces, and 32-channel 10-bit ADC. It operates at up to 64 MHz (31.25 ns instruction cycle), supports 143 GPIOs, and targets automotive powertrain and industrial real-time control systems requiring deterministic DSP-accelerated execution.
For engineers reviewing the ST10F296TR datasheet, ST10F296TR pinout, ST10F296TR application, or ST10F296TR equivalent, this page delivers verified technical context on its dual-CAN timing architecture, MAC-assisted motor control loop performance, external bus arbitration for multi-chip memory expansion, and bootstrap loader support via UART/CAN-critical for ECU firmware update validation and safety-critical BOM continuity.
Technical Context
The ST10F296TR implements a 16-bit CPU core with dedicated 16×16-bit multiply/accumulate (MAC) hardware delivering single-cycle 40-bit accumulation, enabling real-time motor phase current computation. Its interrupt system provides 56 sources with 16 priority levels and 15.6 ns sampling resolution, synchronized to peripheral event controllers for zero-latency sensor data capture.
Memory architecture separates 512 KB IFlash (32-bit fetch) and 320 KB XFlash (16-bit fetch) across five programmable chip-select ranges, with hold-acknowledge bus arbitration supporting external DMA masters. Dual CAN 2.0B modules operate independently-one with 64 message objects, the other with two 32-object banks-enabling concurrent high-speed powertrain and chassis network communication.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit automotive MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon C167CR-LM | 16-bit C166 core, 512 KB Flash, no integrated MAC unit; 40 MHz max clock; single CAN 2.0A interface. | Lacks hardware MAC acceleration and dual-CAN 2.0B support; suitable only for non-motor-control BCM or low-bandwidth gateway roles. | Select only when legacy C166 toolchain compatibility is mandatory and real-time DSP functions are handled externally. |
| Renesas M16C/62P | 16-bit M16C core, 256 KB Flash, 16 KB RAM, single CAN 2.0B; no XFlash extension or peripheral event controller. | Lower memory bandwidth and no hold-acknowledge bus arbitration; insufficient for multi-peripheral real-time data acquisition. | Consider only for cost-sensitive, low-pin-count applications where external memory expansion is unnecessary. |
Compared with C167CR-LM and M16C/62P, the ST10F296TR uniquely combines MAC-accelerated control, dual-CAN 2.0B with 64+32 message objects, and 832 KB Flash/XFlash partitioning-making it the sole option among these three for ASIL-B–compliant motor control with concurrent network domains.

FAQ
Is the ST10F296TR still in active production?
No-the ST10F296TR is marked as obsolete by STMicroelectronics per official documentation. However, Aetrix Electronics maintains a controlled inventory with full traceability, extended lifecycle support, and guaranteed supply for legacy automotive and industrial programs through 2027.
What debugging interfaces does the ST10F296TR support?
The ST10F296TR supports JTAG-based on-chip debugging via the ST-LINK-compatible debug port, enabling real-time variable monitoring, breakpoint insertion, and flash programming without halting CAN or ADC operations-critical for validating timing-critical motor control loops.
Can the internal 1.8 V core regulator be bypassed for external core supply?
No-the embedded 1.8 V regulator is not bypassable; the device requires only a single 5 V ±10% supply applied to VDD pins. The regulator is hardened against automotive load-dump transients and includes internal overtemperature shutdown to protect the CPU core during sustained high-temperature operation.
