Product details
Overview
F276-CEG-P-TR from STMicroelectronics is a 16-bit ST10F276E microcontroller featuring a MAC unit, 832 Kbyte Flash memory (512 KB main + 320 KB extension), and 68 Kbyte RAM (2 KB IRAM + 66 KB XRAM). It operates at up to 64 MHz with 31.25 ns instruction cycle time and integrates dual CAN 2.0B interfaces, 24-channel 10-bit ADC, and programmable external bus for automotive body control and industrial motion systems.
For engineers reviewing the F276-CEG-P-TR datasheet, F276-CEG-P-TR pinout, F276-CEG-P-TR application, or F276-CEG-P-TR equivalent, key selection criteria include its dual-CAN capability, 64 MHz real-time performance with MAC acceleration, 111 GPIOs with hysteresis control, and support for CAN/UART/I²C bootstrap loading in production firmware updates.
Technical Context
The ST10F276E implements a high-performance 16-bit CPU with dedicated 16×16-bit multiply/accumulate unit and 40-bit accumulator, enabling deterministic DSP-like operations in motor control loops. Its interrupt system supports 56 sources across 16 priority levels with 15.6 ns sampling resolution, critical for time-critical CAN message handling and PWM synchronization.
Memory architecture includes linear 16 Mbyte address space (5 Mbyte with CAN/I²C enabled), dual Flash banks with independent 100K erase/program cycles, and on-chip PLL supporting 4–12 MHz crystal input with direct or prescaled clock options. The 32 kHz RTC oscillator and fail-safe features (oscillator watchdog, programmable WDT) ensure robust operation in automotive environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST10F267 | Lower Flash (384 KB) and RAM (32 KB); no extension Flash or XPWM unit. | Suitable for cost-sensitive body electronics without complex motor control. | Select when dual CAN and MAC acceleration are not required; reduces BOM cost by ~18%. |
| Infineon C167CR-LM | 16-bit C166 core; 512 KB Flash, 32 KB RAM; single CAN, no integrated RTC oscillator. | Legacy industrial control where toolchain compatibility outweighs feature parity. | Choose only if existing C166 software investment justifies trade-offs in CAN redundancy and power management. |
Compared with ST10F276E, ST10F267 lacks extension Flash and XPWM-limiting firmware flexibility and advanced motor control-while C167CR-LM offers no dual CAN or on-chip 32 kHz oscillator, increasing external component count and reducing functional safety margin.
