CMS80F261x Enhanced flash memory 8-bit 1T 8051 microcontrollers Datasheet
■System Introduction
▲CMS80F261x 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 a maximum of 64KB program area, 256B RAM space, 4KB XRAM, 1KB Non-volatile data area.
◆With four oscillation modes.
◆It supports three working modes: normal, idle, and sleep, which can effectively reduce power consumption.
◆Built-in low-voltage reset LVR, low-voltage monitoring LVD, watchdog overflow reset and other protection settings can effectively improve the reliability of system operation.
◆With multiple interrupt sources such as external interrupts, timed interrupts and other peripheral interrupts, it can respond to external events in a timely manner and improve the utilization of the MCU.
◆10 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.
◆Up to 8COM and 24SEG LED driver modules are supported.
◆Up to 8COM and 32SEG LCD driver modules are supported.
◆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 high-precision 12-bit ADC and selectable internal reference voltage, up to 2 operational amplifiers, up to 2 comparators, and more abundant analog functions.
