Product details
Overview
F276-CEG-T-TR from STMicroelectronics is a 16-bit ST10F276E microcontroller featuring a MAC unit, 512 KB on-chip Flash (32-bit fetch), 66 KB XRAM, and dual CAN 2.0B interfaces - deployed in automotive body control modules for real-time sensor fusion and actuator coordination.
For engineers reviewing the F276-CEG-T-TR datasheet, F276-CEG-T-TR pinout, F276-CEG-T-TR application, or F276-CEG-T-TR equivalent, key selection criteria include 64 MHz CPU clock timing, 24-channel 10-bit ADC with 3 µs conversion, dual CAN bus support, and LQFP144 package compatibility with industrial temperature range operation.
Technical Context
The ST10F276E implements a 16-bit CISC CPU with hardware MAC coprocessor supporting 16×16-bit multiply and 40-bit accumulate operations in single cycle. Its interrupt system delivers 56 sources across 16 priority levels with 15.6 ns sampling resolution.
Memory architecture includes two independent Flash banks (512 KB main + 320 KB extension) and hierarchical RAM (2 KB IRAM + 66 KB XRAM), mapped into a unified 16 MB linear address space - reduced to 5 MB when CAN or I²C peripherals are enabled.

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 |
|---|---|---|---|
| ST10F269 | Lower Flash (256 KB), no extension Flash; single CAN interface; 48 MHz max clock | Suitable for cost-sensitive BCU nodes with reduced feature set and lower CAN bandwidth requirements | Select when dual CAN and >500 KB Flash are not required; shares same toolchain and pin-compatible footprint in LQFP144 |
| Infineon C167CS-32L | 16-bit C166 core; 512 KB Flash but no integrated MAC; 40 MHz max clock; single CAN | Legacy industrial motion control where ST10 toolchain migration is not feasible | Choose only for brownfield designs migrating from C167; lacks ST10F276E's MAC acceleration and dual CAN timing determinism |

FAQ
What is the maximum operating temperature range for F276-CEG-T-TR?
The F276-CEG-T-TR is rated for operation from -40°C to +125°C ambient temperature, qualified per AEC-Q100 Grade 2 standards for automotive under-hood applications. This rating applies to the LQFP144 package variant and includes full functionality of all peripherals including CAN, ADC, and Flash programming at the upper limit.
Does F276-CEG-T-TR support in-system programming via CAN?
Yes, the device includes a factory-programmed on-chip bootstrap loader that supports firmware updates over CAN bus using standardized protocols. The CAN BSL operates at configurable bit rates (up to 1 Mbps), requires no external hardware, and validates received code integrity before execution or Flash programming.
How many independent PWM channels does F276-CEG-T-TR provide?
F276-CEG-T-TR integrates one 4-channel standard PWM unit and one 4-channel XPWM (extended PWM) unit, totaling eight independently configurable PWM outputs. Each channel supports programmable period, duty cycle, polarity, and dead-time insertion - with XPWM offering enhanced synchronization and fault protection features for motor gate drivers.
Is external memory required to use the full 832 KB Flash capacity?
No. The "832 KB Flash" specification refers to combined on-chip capacity: 512 KB main Flash (32-bit fetch) plus 320 KB extension Flash (16-bit fetch). Both are integrated within the die; no external memory is needed to access either bank. Address space mapping is handled automatically by the external bus controller when enabled.
