STC Microcontroller STC32G12K128 minimum System Board Module

Description

Features: Core • Ultra-high speed 32-bit 8051 Core with single clock per machine cycle, which is called 1T and the speed is about 70 times faster than traditional 8051 • 49 interrupt sources and 4 interrupt priority levels • Online debugging is supported Operating voltage • 1.9V~5.5V • Built-in LDO Operating temperature • -40℃ ~ + 85℃ Flash memory • Up to 128Kbytes of Flash memory to be used for storing user code • Configurable EEPROM size, 512bytes single page for being erased, which can be repeatedly erased more than 100 thousand times. • In-System-Programming, ISP in short, can be used to update the application code. No special programmer is needed. • Online debugging with single chip is supported, and no special emulator is needed. The number of breakpoints is unlimited theoratically. • Support hardware emulation of SWD interface (requires STC-USB Link1 tool) SRAM • 4K bytes internal SRAM (EDATA) • 8K bytes internal extended RAM (internal XDATA • Notes on using xdata: • When defining variables, single-byte variables can be defined in xdata, and multi-byte (2-byte, 4-byte) variables need to be defined in edata. Clock • Internal high precise RC clock IRC(IRC for short), adjustable while ISP and can be divided to lower frequency by user software. • Error:±0.3% (at the temperature 25℃) • -1.35%～+1.30% temperature drift (at the temperature range of -40℃ to +85℃) • -0.76%～+0.98% temperature drift (at the temperature range of -20℃ to 65℃) • Internal 32KHz low speed IRC with larg
