C8051F920功能特征基本介绍:
Supply Voltage: 0.9 to 3.6 V
-One-cell mode supports 0.9-1.8 V operation
-Two-cell mode supports 1.8-3.6 V operation
-Built-in dc-dc converter with 1.8 -3.3 V output (65 mW max) for use in one-cell mode; can supply external devices
-Typical sleep mode current < 0.1 μA; retains state and RAM?contents over full supply range; fast wakeup
-2 built-in brown-out detectors cover sleep and active modes
10-Bit Analog to Digital Converter
-Up to 300 ksps
-Up to 23 external inputs
-External pin or internal VREF (no external capacitor required)
-Built-in temperature sensor
-External conversion start input option
-Autonomous Burst Mode with 16-bit automatic averaging accumulator
Two Comparators
-Programmable hysteresis and response time
-Configurable as interrupt or reset source
-Low current (< 0.5 μA)
-Up to 23 Capacitive Touch Sense inputs
Memory
-4352 bytes internal data RAM (256 + 4K)
-32 kB bytes Flash; In-system programmable in 1024-byte sectors; Full read/write/erase functionality over the entiresupply range
-External memory interface (multiplexed address/data)
On-Chip Debug
-On-chip debug circuitry facilitates full speed, non-intrusive in-system debug (no emulator required)
High-Speed 8051 μC Core
-Pipe-lined instruction architecture; executes 70% of instructions in 1 or 2 system clocks
-25 MIPS peak throughput with 25 MHz clock
-Expanded interrupt handler
Digital Peripherals
-24 port I/O; All 5 V tolerant with programmable drive strength
-Hardware enhanced UART, SPI and SMBus? serial ports available concurrently
-Low power 32-bit smaRTClock (0.5 uA) operates down to 0.9V
-Four general purpose 16-bit counter/timers
-16-bit programmable counter array (PCA) with six capture/com?pare modules and watchdog timer:
?8, 9, 10, 11, or 16-bit PWM
?Rising/falling edge capture
?Frequency output
?Software timer
Clock Sources
-Precision internal oscillators: 24.5 MHz with ±2% accuracy sup?ports UART operation; spread-spectrum mode for reduced EMI
-Low power internal oscillator: 20 MHz
-External oscillator: Crystal, RC, C, CMOS clock
-smaRTClock oscillator: 32.768 kHz crystal or self-oscillate
-Can switch between clock sources on-the-fly; useful in power saving modes
Ultra-Small Package Options
