USB, 25 MIPS, 16 kB Flash, 10-Bit ADC, 32-Pin Mixed-Signal MCU
Analog Peripherals
10-Bit ADC
- ±1 LSB INL; no missing codes
- Programmable throughput up to 200 ksps
- Up to 17 external inputs; programmable as single-ended or differential
- Built-in temperature sensor (±3 °C)
Two Comparators
Internal Voltage Reference: 2.4 V
POR/Brown-out Detector
USB Function Controller
- USB specification 2.0 compliant
- Full-speed (12 Mbps) or low-speed (1.5 Mbps) operation
- Integrated clock recovery; no external crystal required for either full-
speed or low-speed operation
- Supports eight flexible endpoints
- Dedicated 1 kB USB buffer memory
- Integrated transceiver; no external resistors required
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, registers, and USB memory
- Superior performance to emulation systems using ICE-chips, target
pods, and sockets
Operating Voltage: 2.7 to 5.25 V
Temperature Range: –40 to +85 °C
High-Speed 8051 µC Core

system clocks
- Up to 25 MIPS throughput with 25 MHz Clock
- Expanded interrupt handler
Memory
- 1280 bytes data RAM
- 16 kB Flash; in-system programmable in 512-byte sectors (512 bytes
are reserved)
Digital Peripherals
- 25 port I/O; all are 5 V tolerant
- Hardware SMBus™ (I²C™ compatible), SPI™, and UART serial ports
available concurrently
- Programmable 16-bit counter/timer array with five capture/compare
modules
- 4 general-purpose 16-bit counter/timers
Clock Sources
- Internal oscillator: 0.25% accuracy with clock recovery enabled;
supports all USB and UART modes
- External oscillator: Crystal, RC, C, or Clock
- On-chip clock multiplier for USB controller
Voltage Regulator
