ST10F269Z2数据手册ST中文资料规格书

描述 Description

The ST10F269 is a derivative of the STMicroelectronics ST10 family of 16-bit single-chip CMOS microcontrollers. It combines high CPU performance (up to 20 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.

ST10F269 is processed in 0.35µm CMOS technology. The MCU core and the logic is supplied with a 5V to 3.3V on chip voltage regulator on PQFP144 devices (or 5V to 2.7V on TQFP144 devices). The part is supplied with a single 5V supply and I/Os work at 5V.

The device is upward compatible with the ST10F168 device, with the following set of differences:The Multiply/Accumulate unit is available as standard. This MAC unit adds powerful DSP functions to the ST10 architecture, but maintains full compatibility for existing code. Flash control interface is now based on STMicroelectronics third generation of stand-alone Flash memories, with an embedded Erase/Program Controller. This completely frees up the CPU during programming or erasing the Flash. 128-KByte Flash Option Two dedicated pins (DC1 and DC2) on the 144-pin package are used for decoupling the internally generated 3.3V (or 2.7V on TQFP144 devices) core logic supply. Do not connect these two pins to 5.0V external supply. Instead, these pins should be connected to a decoupling capacitor (ceramic type, value ≥ 330 nF). The A/D Converter characteristics are different from previous ST10 derivatives ones. Refer to Section 21.3.1 -. The AC and DC parameters are adapted to the 40MHz maximum CPU frequency on PQFP144 devices (32MHz on TQFP144 devices). The characterization is performed with C L = 50pF max on output pins. Refer to Section 21.3 -. In order to reduce EMC, the rise/fall time and the sink/source capability of the drivers of the I/O pads are programmable. Refer to Section 12.2 -. The Real Time Clock functionality is added. The external interrupt sources can be selected with the EXISEL register. The reset source is identified by a dedicated status bit in the WDTCON register.
