System Overview
C8051F91x-C8051F90x devices are fully integrated mixed-signal System-on-a-Chip MCUs. Highlighted features are listed below. Refer to Table 2.1 for specific product feature selection and part ordering numbers.
• Single/Dual Battery operation with on-chip dc-dc boost converter.
• High-speed pipelined 8051-compatible microcontroller core (up to 25 MIPS)
• In-system, full-speed, non-intrusive debug interface (on-chip)
• 10-bit 300 ksps or 12-bit 75 ksps single-ended ADC with analog multiplexer
• 6-Bit Programmable Current Reference. Resolution can be increased with PWM.
• Precision programmable 24.5 MHz internal oscillator with spread spectrum technology.
• 16 kB or 8 kB of on-chip Flash memory
• 768 bytes of on-chip RAM
• SMBus/I2C, Enhanced UART, and two Enhanced SPI serial interfaces implemented in hardware
• Four general-purpose 16-bit timers
• Programmable Counter/Timer Array (PCA) with six capture/compare modules and Watchdog Timer function
• On-chip Power-On Reset, VDD Monitor, and Temperature Sensor
• Two On-chip Voltage Comparators with 15 Capacitive Touch Sense inputs.
• 16 Port I/O (5 V tolerant)
With on-chip Power-On Reset, VDD monitor, Watchdog Timer, and clock oscillator, the C8051F91x C8051F90x devices are truly stand-alone System-on-a-Chip solutions. The Flash memory can be reprogrammed even in-circuit, providing non-volatile data storage, and also allowing field upgrades of the 8051 firmware. User software has complete control of all peripherals, and may individually shut down any or all peripherals for power savings.
