CMS80F262x Enhanced 1T 8051 microcontroller with flash memory Datasheet
■System Introduction
▲CMS80F262x series is an 8051 core, a 1T instruction system compatible with MCS-51, and a general IO type 8-bit chip. The operating frequency can reach up to 48MHz. The MCU has the following characteristics:
◆With 64KB program area, 256B RAM space, 4KB XRAM, 1KB Data FLASH area.
◆With four oscillation modes.
◆It supports four working modes: normal, idle 1, idle 2, and sleep, which can effectively reduce power consumption.
◆Built-in low-voltage reset LVR, low-voltage detection LVD, watchdog overflow reset, window watchdog reset and other protection settings can effectively improve the reliability of system operation.
◆With multiple interrupt sources such as external interrupts, timer interrupts and other peripheral interrupts, it can respond to external events in a timely manner and improve the utilization of the MCU.
◆11 timers, which can realize functions such as timing, counting, input capture, output comparison, timing wake-up, and baud rate generator.
◆With hardware multiplication and division unit MDU, cyclic redundancy check unit CRC.
◆LED driver module supports up to 8COM and 24SEG.
◆LCD driver module supports up to 8COM and 32SEG.
◆6-channel 16-bit PWM, supports independent, complementary, and synchronous three-mode output, and has hardware brake function, dead zone control function, mask output and other functions.
◆With 1 I2C, 1 SPI, and 4 UART communication modules, it can realize data transmission between the system and other devices.
◆With high-precision 12-bit ADC and selectable internal reference voltage, up to 2 comparators, and more abundant analog functions.
