CMS80F261x Datasheet Enhanced Flash 8bit 1T 8051-Microcontroller
■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.
