proximity sensing
- Fast 40 µs per channel conversion time
- 16-bit resolution
- Up to 16 input channels
- Auto-scan and wake-on-touch
- Auto-accumulate 4x, 8x, 16, 32x, and 64x samples
Analog Peripherals
- 10-Bit ADC
Up to 500 ksps
Up to 16 external single-ended inputs
VREF from on-chip VREF, external pin or VDD
Internal or external start of conversion source
Built-in temperature sensor
- Comparator
Programmable hysteresis and response time
Configurable as interrupt or reset source
On-Chip Debug
- On-chip debug circuitry facilitates full speed, non-
intrusive in-system debug (no emulator required)
- Provides breakpoints, single stepping,
inspect/modify memory and registers
- Superior performance to emulation systems using
ICE-chips, target pods, and sockets
- Low cost, complete development kit
C8051F80x-83x
Mixed Signal ISP Flash MCU Family
High-Speed 8051 µC Core
- Pipelined instruction architecture; executes 70% of
instructions in 1 or 2 system clocks
- Up to 25 MIPS throughput with 25 MHz clock
- Expanded interrupt handler
Memory
- Up to 512 bytes internal data RAM (256 + 256)
- Up to 16 kB Flash; In-system programmable in
512-byte sectors
Digital Peripherals
- 17 or 13 Port I/O with high sink current
- Hardware enhanced UART, SMBus™ (I2C compati-
ble), and enhanced SPI™ serial ports
- Three general purpose 16-bit counter/timers
- 16-Bit programmable counter array (PCA) with 3
capture/compare modules and enhanced PWM
functionality
