ST10F276-6QR3 Présentation
A 16-bit microcontroller (MCU) is a single-chip computer with a 16-bit data path, integrating a CPU, memory, and peripherals. The ST10 family is a derivative of the Siemens 80C166 architecture, offering high instruction throughput and rich peripheral set. In the system hierarchy, a 16-bit MCU sits between 8-bit and 32-bit devices, providing a balance of performance and power efficiency for real-time control tasks.
Key features include a 5-stage pipeline, 16-channel A/D converter with 10-bit resolution, 2 CAN 2.0B interfaces, 2 USARTs, and a 4-channel PWM unit. The device also includes a watchdog timer, 16 interrupt priority levels, and an on-chip bootstrap loader. The ST10 core executes most instructions in one clock cycle, achieving up to 16 MIPS at 32 MHz.
The ST10F276-6QR3 is designed for harsh environments, with an operating temperature range of -40°C to +125°C. It is AEC-Q100 qualified for automotive applications, ensuring reliability under extreme conditions. The Flash memory supports in-application programming (IAP) and in-circuit programming (ICP), facilitating firmware updates in the field.
Typical applications include engine control units (ECUs), transmission control, body control modules, and industrial automation systems. The dual CAN interfaces make it ideal for automotive networking, while the high-resolution ADC and PWM unit support motor control and sensor interfacing.
When designing with this MCU, ensure proper decoupling of the power supply pins and a stable clock source. The device requires an external crystal or oscillator for precise timing. For EMI-sensitive designs, use the internal PLL to reduce radiated emissions.

Principaux différenciateurs
- Higher clock speed (32 MHz vs 20 MHz) (vs ST10F276-4T3)
- Larger Flash memory (832 KB vs 512 KB) (vs ST10F276-4T3)
- Same package and pinout (vs ST10F276-4T3)
Notes de conception
The ST10F276-6QR3 operates from a 4.5V to 5.5V supply. Use a stable 5V rail with adequate decoupling: place a 100nF ceramic capacitor close to each VDD pin and a 10uF bulk capacitor near the power entry. Ensure the ground plane is solid to minimize noise and voltage drops.
For the LQFP-144 package, use a 0.5mm pitch land pattern. Provide a thermal pad on the PCB for heat dissipation, even though the package may not have an exposed pad. Route high-speed signals away from the crystal oscillator and analog inputs to reduce interference.
Do not exceed the absolute maximum ratings, especially on I/O pins. Use series resistors for external connections to limit current. Ensure the reset circuit is robust with a proper power-on reset delay. For CAN communication, use appropriate transceivers and termination resistors.
