汽车级 ST10F252M 16位MCU的256KB Flash和16kb RAM
The ST10F252M is a new derivative of the STMicroelectronics ST10 family of 16-bit singlechip CMOS microcontrollers.
The ST10F252M combines high CPU performance (up to 24 million instructions per second) with high peripheral functionality and enhanced I/O capabilities. It also provides on-chip high-speed single voltage Flash memory, on-chip high-speed RAM, and clock generation via PLL.
The ST10F252M is processed in 0.18 μm CMOSM8 technology. The MCU core and the logic is supplied with a 5 V to 1.8 V on-chip voltage regulator. The part is supplied with a single 5 V supply and I/Os work at 5 V.
The ST10F252M is an optimized version of ST10F252E device, upward compatible with the following set of differences.
- The AC and DC parameters are modified due to a difference in the maximum CPU frequency. Refer to Section 27.5 and Section 27.8 for detailed description.
- XASC, XSSC, XPWM and I2C have been changed. Refer to Chapter 13.
- No external bus is available when all 16 ADC channels are selected.
- Pin T3EUD is added for encoder interface as alternate function of P1H.0.
- A/D Converter has 16 channels, 10 are on standard Port5, 6 channels on Port0.
- XPERCON register bit mapping modified according to new peripherals implementation.
- External bus NO ARBITRATION and READY, hold and ready pins not available
- On-chip low power oscillator, 32 KHz, is no longer available.
