Analog Peripherals
    - 12-Bit ADC
      • Up to 200 ksps • Up to 25 external single-ended inputs
      • VREF from on-chip VREF, external pin or VDD
      • Internal or external start of conversion source
      • Built-in temperature sensor
    - Two Comparators
      • Programmable hysteresis and response time
      • Configurable as interrupt or reset source
      • Low current
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
Supply Voltage 1.8 to 5.25 V
    - Typical operating current: 19 mA at 50 MHz; Typical stop mode current: 1 µA
High-Speed 8051 µC Core
    - Pipelined instruction architecture; executes 70% of instructions in 1 or 2 system clocks
    - Up to 50 MIPS throughput with 50 MHz clock
    - Expanded interrupt handler
Memory
    - 1280 bytes internal data RAM (256 + 1024 XRAM)
