Product details
Overview
ST10F272M-4T3 from STMicroelectronics is a 16-bit automotive-grade MCU featuring a 40 MHz CPU, 256 Kbyte Flash memory, 20 Kbyte RAM (2 Kbyte IRAM + 18 Kbyte XRAM), dual CAN 2.0B interfaces, and a 24-channel 10-bit ADC - deployed in engine control units and industrial motion controllers requiring deterministic real-time response.
For engineers reviewing the ST10F272M-4T3 datasheet, ST10F272M-4T3 pinout, ST10F272M-4T3 application, or ST10F272M-4T3 equivalent, key selection considerations include its 16-priority-level interrupt system with 56 sources, MAC unit for DSP-intensive control loops, fail-safe watchdog/oscillator watchdog, and -40°C to +125°C operation in LQFP144 package.
Technical Context
The ST10F272M-4T3 integrates a 16-bit ST10 CPU core with hardware multiply-accumulate (16×16 → 40-bit), single-cycle context switching, and enhanced bit manipulation - enabling cycle-accurate motor commutation and sensor fusion. Its memory architecture supports up to 16 Mbyte linear addressing, with configurable external bus (5 chip-selects, hold/acknowledge arbitration) and dual-bank Flash with 100K erase/program cycles.
Real-time capability is reinforced by an 8-channel peripheral event controller for zero-latency data transfer, two multi-functional timer units (5 timers total), dual 16-channel CAPCOM units, and two independent CAN 2.0B modules supporting 64-message or dual 32-message buffers - all synchronized to a PLL-driven 40 MHz clock derived from 4–8 MHz crystal or external clock input.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | 16-bit ST10 with MAC unit: enables real-time PID loop execution and sensor data filtering without software overhead. |
| Max Clock Speed | 40 MHz (50 ns instruction cycle): delivers deterministic timing for safety-critical engine timing and valve actuation. |
| Flash Memory | 256 Kbyte single-voltage Flash: supports in-field firmware updates and secure boot via on-chip protection registers. |
| RAM | 20 Kbyte total (2 Kbyte IRAM + 18 Kbyte XRAM): sufficient for real-time control stacks, CAN message buffers, and ADC sample queues. |
| ADC | 24-channel 10-bit ADC (16 ch ±2 LSB, 8 ch ±5 LSB, 4.85 µs min conversion): meets ASIL-B sampling requirements for throttle position and temperature sensing. |
| CAN Interfaces | 2 × CAN 2.0B (C-CAN): supports redundant bus architectures or separate powertrain/diagnostic networks with 64-message buffer. |
| Operating Temp | -40°C to +125°C: qualified for under-hood automotive ECU deployment without derating. |
| Supply Voltage | 5 V ±10% with embedded 1.8 V core regulator: simplifies power design and eliminates external core LDO. |
Pinout & Package
LQFP144 (20 × 20 mm, 0.5 mm pitch) with exposed thermal pad - optimized for high-pin-count automotive microcontrollers requiring robust thermal dissipation and EMI resilience.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply / Ground | Dedicated analog/digital power pins with separate ground planes reduce noise coupling in mixed-signal operation. |
| XTAL1/XTAL2 | Crystal oscillator input/output | Supports 4–8 MHz fundamental-mode crystals for precise clock generation; internal oscillator watchdog monitors stability. |
| CANH/CANL (CAN1, CAN2) | Differential CAN bus interface | Integrated CAN transceiver drivers compliant with ISO 11898-2; support bus fault detection and automatic retransmission. |
| AD0–AD23 | Analog input channels | 24 dedicated ADC inputs with programmable hysteresis and selectable reference (VREFH/VREFL) for sensor signal conditioning. |
| P0–P15, P20–P27, P30–P37, P40–P47 | General-purpose I/O | 111 GPIO lines individually configurable as push-pull, open-drain, or high-impedance input with threshold control for noisy environments. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip PLL with 4–8 MHz input | Generates stable 40 MHz system clock without external frequency multipliers; reduces BOM cost and board space. |
| Programmable external bus | 5 chip-select signals and hold/acknowledge arbitration enable seamless interfacing with external Flash, SRAM, or peripherals at up to 20 MHz. |
| Fail-safe protection suite | Includes programmable watchdog timer, oscillator watchdog, and reset circuitry with asynchronous/synchronous/warm reset modes per ISO 26262 ASIL-B. |
| Bootstrap loader with ABM/SBM | Enables field firmware updates via ASC or CAN; alternate boot mode (ABM) allows fallback to known-good image after failed update. |
| X-peripheral clock gating | Reduces dynamic power consumption by disabling clocks to unused peripherals (e.g., disabled CAPCOM or PWM) without software intervention. |
Applications
| Engine Control Unit (ECU) | Industrial Motion Controller |

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 C167CS-LM | 16-bit C166 core, 33 MHz max, 256 Kbyte Flash, no integrated CAN - requires external CAN controller. | Lacks dual CAN and failsafe watchdog; suitable only where CAN is implemented externally or not required. | Select only if legacy C166 toolchain compatibility is mandatory and CAN functionality is handled off-chip. |
| NXP S12XEP100 | 16-bit HCS12X core, 50 MHz, 1 MB Flash, 64 Kbyte RAM, 3× CAN, but no MAC unit or XRAM expansion. | Higher Flash/RAM capacity but lacks hardware MAC for DSP tasks; uses different interrupt model (priority-based vs. vectorized). | Prefer when large code footprint dominates over real-time DSP performance; avoid for motor control requiring MAC acceleration. |
Compared with C167CS-LM and S12XEP100, the ST10F272M-4T3 uniquely balances deterministic real-time execution (via MAC and 25 ns interrupt sampling), dual-CAN redundancy, and automotive temperature resilience - making it optimal for safety-critical powertrain applications where hardware-accelerated control loops are essential.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time of the ST10F272M-4T3?
The ST10F272M-4T3 operates at a maximum CPU clock frequency of 40 MHz, delivering a 50 ns instruction cycle time. This timing is achieved using the on-chip PLL locked to a 4–8 MHz crystal or external clock source, and is validated across the full -40°C to +125°C temperature range per datasheet Section 24.8.7.
Does the ST10F272M-4T3 support in-system programming (ISP) of its Flash memory?
Yes - the ST10F272M-4T3 includes an on-chip bootstrap loader supporting ISP via ASC or CAN interfaces. It implements alternate boot mode (ABM) and selective boot mode (SBM) with signature integrity checks, enabling secure field firmware updates without external programmers per datasheet Sections 6.1–6.3.
How many CAN interfaces does the ST10F272M-4T3 integrate, and what protocol versions are supported?
The ST10F272M-4T3 integrates two independent CAN 2.0B-compliant interfaces (C-CAN modules), each supporting standard and extended identifiers, message objects (64 total or 2×32 in dual-bus mode), and automatic retransmission. Both modules meet ISO 11898-1 physical layer timing requirements per datasheet Section 17.
What power-saving modes are available, and which retain RAM content during low-power operation?
The ST10F272M-4T3 offers Idle, Power-down, and Stand-by modes. In Power-down mode (Section 21.2), both IRAM and XRAM contents are retained while CPU and most peripherals halt; Stand-by mode retains RAM and RTC operation with ultra-low current draw, enabled via dedicated control bits in the power control register.
