AT32F415
Overview
- Core: ARM® 32-bit Cortex®-M4 CPU - 150 MHz maximum frequency, with a memory protection unit (MPU) - Single-cycle multiplication and hardware division - DSP instructions
- Memories - 64 to 256 Kbytes of internal Flash memory - 18 Kbytes of boot code area used as a Bootloader - sLib: configurable part of main Flash set as a library area with code executable but secured, non-readable - 32 Kbytes of SRAM
- Power control (PWC) - 2.6 to 3.6 V supply - Power on reset (POR), low voltage reset (LVR), and power voltage monitoring (PVM) - Low power modes: Sleep, Deepsleep, and Standby modes - VBAT for LEXT, ERTC and 20 x 32-bit battery powered registers (BPR)
- Clock and reset management (CRM) - 4 to 25 MHz crystal (HEXT) - 48 MHz internal factory-trimmed high speed clock (HICK), 1 % accuracy at TA = 25 °C and 2 % accuracy at TA = -40 to +105 °C - PLL flexible 31 to 500 multiplication and 1 to 15 division factor - 32 kHz crystal (LEXT) - Low speed internal clock (LICK)
- Analog - 1 x 12-bit 2 MSPS A/D converter, up to 16 input channels - Temperature sensor (VTS) and internal reference voltage (VINTRV) - 2 x comparators (CMP)
- DMA: two 7-channel DMA controllers
- Up to 55 fast GPIOs - All mappable on 16 external interrupts (EXINT) - Almost all 5 V-tolerant
- Up to 11 timers (TMR) - 1 x 16-bit 7-channel advanced timer, 3 pairs of complementray channel PWM outputs with dead-time generator and emergency stop - Up to 5 x 16-bit and 2 x 32-bit timers, each with 4 IC/OC/PWM or pulse counter and quadrature (incremental) encoder input - 2 x watchdog timers (general WDT and windowed WWDT) - SysTick timer: a 24-bit downcounter
- ERTC: enhanced RTC with auto-wakeup, alarm, subsecond accuracy, and hardware calendar; supports calibration
- Up to 12
