Key Features

• Core  M8051-compatible 8-bit CISC CPU running with a 16 MHz internal RC oscillator (±2.0%, TA = 0 ~ +50 °C); 2 clocks per cycle architecture.
• Memory  64 Kbytes of on-chip Flash program memory with self read/write capability and 4,352 bytes of SRAM (256 bytes IRAM + 4,096 bytes XRAM) for data and stack.
• Analog  12-bit A/D converter with 15 input channels for precise sensor measurement and analog interfacing.
• Timers & PWM  Multiple timers including 8/16-bit timers, 16-bit and 8-bit PWM channels, and a watchdog/watch timer for real-time control and safety functions.
• Connectivity  Multiple serial interfaces including SPI (2 channels), UART (3 channels), and USI (2 sets supporting UART/SPI/I2C modes) to connect sensors, peripherals, and external devices.
• System Reliability & Power  On-chip Power-On Reset (POR), low-voltage detect/reset (LVD/LVR), LDO support, and a watchdog timer ensure dependable operation across power events.
• I/O Density  Up to 61 programmable I/O lines in the 64-pin package for flexible system-level integration.
• Operating Range & Packaging  Wide supply range of 2.2 – 5.5 V, operating temperature −40 – 85 °C, and available in a 64-LQFP-1414 surface-mount package for compact board designs.

Typical Applications

• Home Appliances  Control and user-interface tasks for appliances, using integrated ADC channels and timers for sensor and actuator control.
• Industrial Control  Embedded control functions in industrial equipment where robust I/O, watchdog supervision, and wide voltage/temperature ranges are required.
• Embedded Control Systems  General-purpose embedded designs that benefit from on-chip Flash, multiple serial interfaces, and integrated analog peripherals for sensor interfacing and real-time control.

Unique Advantages

• Highly integrated peripherals: 12-bit ADC, multiple timers, PWM, UART/SPI/USI interfaces and CRC generator reduce external component count and simplify BOM.
• Flexible memory architecture: 64 Kbytes of Flash with in-system programming and a combined IRAM/XRAM arrangement (256 B IRAM + 4,096 B XRAM) for code and data partitioning.
• Wide supply and temperature range: 2.2 – 5.5 V operation and −40 – 85 °C rating support a broad set of deployment environments.
• Robust system control features: On-chip POR, low-voltage detection, watchdog timer and LDO support enhance reliability in power-sensitive applications.
• Compact system integration: 61 I/O lines in a 64-LQFP-1414 surface-mount package enable dense, space-constrained PCB layouts.
