Product details
Overview
F272-BAG-T-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-designed for automotive body control modules requiring real-time deterministic response, fail-safe operation, and multi-bus connectivity.
For engineers reviewing the F272-BAG-T-TR datasheet, F272-BAG-T-TR pinout, F272-BAG-T-TR application, or F272-BAG-T-TR equivalent, this MCU delivers verified 10-bit ADC conversion in ≤3 μs, 111 GPIO with programmable hysteresis, and integrated PLL with 4–8 MHz crystal support-critical for ECU firmware validation, CAN gateway design, and powertrain subsystem integration.
Technical Context
The ST10F272B implements a 16-bit CISC CPU with MAC unit supporting 16×16-bit multiply and 40-bit accumulate in single cycle, enabling real-time motor control algorithms. Its interrupt system provides 56 sources with 16 priority levels and 15.6 ns sampling resolution for time-critical event handling.
Memory architecture supports up to 16 Mbyte linear address space (5 Mbyte with CAN/I²C enabled), with on-chip 256 Kbyte Flash (100K erase/program cycles) and configurable external bus interface including five chip-select signals and hold-acknowledge arbitration-optimized for mixed-code/data execution in safety-critical embedded systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | 16-bit ST10 CISC with DSP extensions; enables deterministic real-time control loops without external co-processor. |
| Max Clock Speed | 64 MHz (31.25 ns instruction cycle); sustains full peripheral operation including dual CAN and 24-channel ADC. |
| Flash Memory | 256 Kbyte single-voltage Flash with erase/program controller; supports in-system programming and 100K endurance cycles. |
| RAM | 12 Kbyte XRAM + 2 Kbyte IRAM; separates critical real-time data (IRAM) from application buffers (XRAM). |
| ADC | 24-channel 10-bit SAR ADC with ≤3 μs conversion time; meets automotive sensor acquisition timing for throttle, temperature, and position feedback. |

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 |
|---|---|---|---|
| ST10F276M4B1 | Same ST10 core, 512 Kbyte Flash, 20 Kbyte RAM, LQFP176 package; lacks second CAN controller. | Targeted at higher-code-footprint applications without dual-CAN requirement (e.g., infotainment subcontrollers). | Select when larger Flash is needed but dual-CAN is unnecessary; requires PCB redesign due to 176-pin footprint. |
| Infineon C167CR-LM | 16-bit C166 family; 256 Kbyte Flash, 16 Kbyte RAM, single CAN 2.0B; no integrated PLL or 32 kHz RTC oscillator. | Suitable for cost-sensitive legacy designs where external clock generation and RTC are acceptable. | Choose only if existing toolchain and board layout are based on C166 architecture; lacks ST10F272B's fail-safe oscillator watchdog. |
Compared with ST10F272B, ST10F276M4B1 offers double Flash capacity but removes one CAN interface and increases pin count, while C167CR-LM trades integrated clock/RTC reliability for broader legacy ecosystem support-making F272-BAG-T-TR optimal for new dual-CAN automotive designs requiring fail-safe timing.

FAQ
What is the maximum operating temperature range for F272-BAG-T-TR?
The F272-BAG-T-TR is rated for −40 °C to +125 °C ambient operation per AEC-Q100 Grade 2 qualification, validated across full voltage (4.5–5.5 V) and clock (0–64 MHz) ranges-ensuring reliability in under-hood automotive environments.
Does F272-BAG-T-TR support in-application programming (IAP) of Flash memory?
Yes, the device supports IAP via its embedded Flash controller with dedicated registers (FCON0/FCON1, FADR, FDAT). Verified write/erase sequences allow firmware updates without halting CPU execution, provided proper sector locking and access protection are configured per Section 5.5 of the datasheet.
How many CAN message objects does the C-CAN module support in F272-BAG-T-TR?
The dual C-CAN modules support either 64 total message objects in shared mode or 32 objects per CAN channel in split mode, with configurable acceptance filtering, transmit prioritization, and automatic retransmission-fully compliant with CAN 2.0B specification up to 1 Mbps.
Is the 32 kHz RTC oscillator in F272-BAG-T-TR temperature-compensated?
No, the on-chip 32 kHz oscillator is an uncalibrated RC type intended for low-power timekeeping during stand-by mode; it exhibits ±20% frequency tolerance over temperature and voltage. For precision RTC, an external 32.768 kHz crystal must be connected to XTAL1/XTAL2 in low-frequency mode.
