1 General Description

These devices are high performance, low power consumption 32-bit microcontrollers based around

an Arm® Cortex®-M3 processor core. The Cortex®-M3 is a next-generation processor core which

is tightly coupled with Nested Vectored Interrupt Controller (NVIC), SysTick timer, and includes

advanced debug support.

The devices operate at a frequency of up to 96 MHz with a Flash accelerator to obtain maximum

efficiency. They provide up to 256 KB of embedded Flash memory for code/data storage and 128 KB

of embedded SRAM memory for system operation and application program usage. A variety of

peripherals, such as ADC, I2C, USART, UART, SPI, I2S, PDMA, GPTM, MCTM, SCI, EBI, CRC-

16/32, AES-128/256, USB2.0 FS, SDIO, CSIF and SWJ-DP (Serial Wire and JTAG Debug Port),

etc., are also implemented in the devices series. Several power saving modes provide the flexibility

for maximum optimization between wakeup latency and power consumption, an especially

important consideration in low power applications.

The above features ensure that the devices are suitable for use in a wide range of applications,

especially in areas such as white goods application control, power monitors, alarm systems,

consumer products, handheld equipment, data logging applications, motor control, fingerprint

recognition and so on.
