It combines a large code and data memory footprint with extensive peripheral sets to support advanced consumer-electronics control, sensor interfacing and user-interface functions.

Key Features

• Core Arm® 32-bit Cortex®-M3 core with operation up to 75 MHz for responsive control and real-time tasks.
• Memory Up to 768 KB code Flash (dual-bank) with ECC, 32 KB data Flash and up to 24 KB SRAM; supports read-while-write (RWW) for seamless firmware updates and reliable code storage.
• Power and Clock Operating voltage 3.0 V to 5.5 V with power-on/power-down reset (POR/LVR/LVI) and low-power modes (SLEEP, DEEP-SLEEP). Integrated clock sources include a 16 MHz internal oscillator, 1 MHz ring oscillator and support for external crystal references with a PLL to 75 MHz.
• Timers and PWM Rich timing resources including ten 16-bit timers (with input capture and output channels), one 32-bit timer, a 32-bit free-run timer and eight 16-bit PWM generators for motor, actuator and timing control. Includes a 32-bit watchdog timer with multiple prescalers for system supervision.
• Analog Single SAR 12-bit ADC with up to 16 analog input channels and 70 ksps throughput (max ~15 µs per channel under specified conditions), supporting single conversions and timer-triggered sampling.
• Connectivity and I/O Multiple serial interfaces: 4× UART, 2× SPI and 2× I2C, plus SWD/JTAG debug support. Up to 90 general-purpose I/O pins with multi-function mapping and external interrupt capability. Integrated LED driver / high-current ports (16) simplify display and indicator designs.
• System Reliability Flash memory ECC and dual-bank Flash architecture enhance code integrity and update flexibility. Built-in Low-Voltage Detector (LVD) with reset/interrupt and wake-up support improves resilience across power events.
• Package and Environmental Available in a 100-MQFP package (14×20 mm, 0.65 mm pitch) for surface-mount assembly; specified operating temperature range −40 °C to 85 °C for broad commercial and household deployment.

Typical Applications
