C8051F316
25 MIPS, 16 kB Flash,10-Bit ADC, 24-Pin Mixed-Signal MCU Analog Peripherals
10-Bit ADC
High-Speed 8051 C Core
Pipelined instruction architecture; executes 70% of instructions in 1 or 2 system clocks Up to 25 MIPS throughput with 25 MHz system clock Expanded interrupt handler
-
1 LSB INL; no missing codes Programmable throughput up to 200 ksps Up to 13 external inputs VREF from external pin or VDD Internal or external start of conversion sources Data-dependent windowed interrupt generator
Memory
1280 bytes data RAM (1024 + 256) 16 kB Flash; in-system programmable in 512-byte sectors (512 bytes are reserved)
Built-in temperature sensor (3 C) Comparator
Programmable hysteresis and response time Configurable to generate interrupts or reset Low current (<0.5 A)
Digital Peripherals
21 port I/O; all are 5 V tolerant 1 Enhanced Hardware SMBusTM (I2CTM compatible) and UART serial port Programmable 16-bit counter/timer array with three capture/compare modules, WDT 5 general-purpose 16-bit counter/timers Dedicated watchdog timer; bidirectional reset Real-time clock mode for maximum power saving
POR/Brown-Out Detector
On-Chip Debug
On-chip debug circuitry facilitates full speed, non-intrusive in-system debug (no emulator required) Provides breakpoints, single stepping, watchpoints Inspect/modify memory, registers, and stack Superior performance to emulation systems using ICE-chips, target pods, and sockets
Clock Sources
Internal oscillator: 24.5 MHz, 2% accuracy supports UART operation External oscillator: Crystal, RC, C, or Clock (1 or 2 pin modes) Can switch between clock sources on-the-fly
Supply Voltage: 2.7 to 3.6 V
Typical operating current: 5 mA at 25 MHz Typical: 11 A at 32 kHz Target stop mode current: <0.1 A
