Overview
- Core: ARM® 32-bit Cortex®-M4 CPU with FPU - 288 MHz maximum frequency, with a memory protection unit (MPU), single-cycle multiplication and hardware division - Floating point unit (FPU) - DSP instructions
- Memories - 256 to 4032 Kbytes of internal Flash memory - sLib: configurable part of main Flash set as a library area with code executable but secured, non-readable - Default 384 Kbytes of SRAM, configurable up to maximum 512 Kbytes - External memory controller (XMC) with 16bit data bus. Supports CF card, SRAM, PSRAM, NOR, NAND, and SDRAM memories - Up to 2 x QSPI interfaces for external SPI Flash or SPI RAM extension, and memory mapping mode
- XMC as LCD parallel interface, compatible with 8080/6800 modes
- Power control (PWC) - 2.6 V ~ 3.6 V power supply - Power on reset (POR), low voltage reset (LVR), and power voltage monitoring (PVM) - Low power: Sleep, Deepsleep, and Standby modes - VBAT supply for LEXT, ERTC and 20 x 32bit battery powered registers (BPR)
- Clock and reset management (CRM) - 4 to 25 MHz crystal oscillator (HEXT) - 48 MHz internal factory-trimmed clock (HICK), accuracy ±1 % at TA = 25 °C and ±2.5 % at TA = -40 to +105 °C, with automatic clock calibration (ACC) - PLL flexible multiplication and division factor - 32 kHz crystal (LEXT) - Low speed internal clock (LICK)
- Analog - 3 x 12-bit 5.33 MSPS A/D converters, up to 24 input channels, 12/10/8/6-bit configurable resolution, hardware oversampling up to equivalent 16-bit resolution - Temperature sensor (VTS), internal reference voltage (VINTRV), VBAT battery voltage monitor (VBAT/4) - 2 x 12-bit D/A converters
- DMA - 2 x general-purpose DMAs and 1 x EDMA - 22 channels in all
