Product details
Overview
F272-BAG-P-TR from STMicroelectronics is a 16-bit ST10F272B microcontroller featuring 256 Kbyte Flash memory, 12 Kbyte RAM, dual CAN 2.0B interfaces, and a 64 MHz CPU clock with 31.25 ns instruction cycle time-designed for real-time automotive body control and industrial motion control applications.
For engineers reviewing the F272-BAG-P-TR datasheet, F272-BAG-P-TR pinout, F272-BAG-P-TR application, or F272-BAG-P-TR equivalent, this MCU delivers deterministic interrupt response (15.6 ns sampling), 24-channel 10-bit ADC (3 μs conversion), and integrated MAC unit for motor control loop computation.
Technical Context
The ST10F272B implements a 16-bit CISC CPU with DSP extensions including a dedicated 16×16-bit MAC unit and 40-bit accumulator, enabling single-cycle multiply-accumulate operations critical for digital power supply and servo control algorithms.
Its memory architecture supports up to 16 Mbyte linear address space (5 Mbyte with CAN/I²C enabled), with programmable external bus configuration, five chip-select signals, and hold-acknowledge arbitration-optimized for interfacing with external SRAM, EPROM, or ASIC peripherals in embedded control systems.

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 |
|---|---|---|---|
| ST10F276M4 | Same ST10 core, 512 Kbyte Flash, 20 Kbyte XRAM, but LQFP144 package and no integrated 32 kHz oscillator | Higher code density for complex diagnostics; requires external RTC crystal | Select when firmware size exceeds 256 Kbyte and board layout favors thinner LQFP package |
| Infineon C167CR-LM | 16-bit C166 family core, 256 Kbyte Flash, 16 Kbyte RAM, single CAN, no MAC unit | Lacks hardware multiply-accumulate-requires software emulation for motor control math | Choose only if existing toolchain compatibility outweighs performance loss in real-time control loops |
Compared with ST10F272B, ST10F276M4 offers double Flash capacity at cost of RTC integration, while C167CR-LM trades MAC acceleration for broader compiler support-making F272-BAG-P-TR optimal for cost-sensitive, latency-critical CAN+motor control designs.

FAQ
What is the maximum operating temperature range for F272-BAG-P-TR?
The F272-BAG-P-TR is rated for industrial temperature range: –40 °C to +85 °C. This specification is confirmed in Section 24.2 (Recommended Operating Conditions) of the official STMicroelectronics datasheet Doc ID 11917 Rev 5, and applies to both PQFP144 and LQFP144 variants of the ST10F272B.
Does F272-BAG-P-TR support in-system programming via CAN?
Yes-F272-BAG-P-TR includes an on-chip bootstrap loader that supports CAN-based firmware updates. The C-CAN module operates in boot mode to receive and verify new application code over CAN bus without requiring external programming hardware, as documented in Section 6 of the datasheet.
How many priority levels does the interrupt controller support?
The interrupt system provides 16 programmable priority levels across 56 interrupt sources, with sampling down to 15.6 ns. This enables precise nesting and preemption for time-critical tasks such as PWM synchronization and ADC trigger handling, per Section 9 of the datasheet.
Is the 32 kHz oscillator integrated or external?
F272-BAG-P-TR integrates a 32 kHz RC oscillator for real-time clock operation, eliminating the need for an external crystal. This on-chip oscillator is explicitly listed in Section 18 (Real Time Clock) and Section 24.8.12 of the datasheet, and remains active during stand-by mode.
