Brown-Out Detector and POR Circuitry

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 full-speed or
      low-speed
   - Supports eight flexible endpoints
   - 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, and registers
   - Superior performance to emulation systems using ICE-chips, target
      pods, and sockets

Supply Voltage: 1.8 to 3.6 V
   - Voltages from 2.7 to 5.25 V supported using on-chip voltage regulators
Temperature Range: –40 to +85 °C

High-Speed 8051 µC Core
   - Pipelined instruction architecture; executes 70% of instructions in 1 or 2
      system clocks
   - Up to 48 MIPS operation
   - Expanded interrupt handler
  
Memory
   - 4352 or 2304 Bytes RAM
   - 64 or 32 kB Flash; In-system programmable in 512-byte sectors
  
Digital Peripherals
   - 40/25 Port I/O; All 5 V tolerant with high sink current
   - Hardware enhanced SPI™, two I²C/SMBus™, and two enhanced UART
      serial ports
   - Six general purpose 16-bit counter/timers
   - 16-bit programmable counter array (PCA) with five capture/compare
      modules
   - External Memory Interface (EMIF)
   - Clock Sources
  
Clock Sources
   - Internal Oscillator: ±0.25% accuracy with clock recovery enabled.
      Supports all USB and UART modes
   - External Oscillator: Crystal, RC, C, or clock (1 or 2 Pin modes)
   - Low Frequency (80 kHz) Internal Oscillator
   - Can switch between clock sources on-the-fly

Package
   - 48-pin TQFP (C8051F380/2/4/6)
   - 32-pin LQFP (C8051F381/3/5)
   - 5x5 mm 32-pin QFN (C8051F381/3/5)
