Product Summary

The C8051F340-GQ is an Universal Serial Bus Controller (USB0). It is a USB 2.0 compliant Full or Low Speed function with integrated transceiver and endpoint FIFO RAM. A total of eight endpoint pipes are available: a bi-directional control endpoint (Endpoint0) and three pairs of IN/OUT endpoints (Endpoints1-3 IN/OUT).

Parametrics

C8051F340-GQ absolute maximum ratings: (1)Ambient temperature under bias: –55 to 125℃; (2)Storage Temperature: –65 to 150℃; (3)Voltage on any Port I/O Pin or /RST with respect to GND: –0.3 to 5.8 V; (4)Voltage on VDD with respect to GND: –0.3 to 4.2 V; (5)Maximum Total current through VDD and GND: 500 mA; (6)Maximum output current sunk by /RST or any Port pin: 100 mA.

Features

C8051F340-GQ features: (1)USB specification 2.0 compliant; (2)Full speed (12 Mbps) or low speed (1.5 Mbps) operation; (3)Integrated clock recovery; no external crystal required for full speed or low speed; (4)Supports eight flexible endpoints; (5)1 kB USB buffer memory; (6)Integrated transceiver; no external resistors required; (7)40/25 Port I/O; All 5 V tolerant with high sink current; (8)Hardware enhanced SPI, SMBus, and one or two enhanced UART serial ports; (9)Four general purpose 16-bit counter/timers; (10)16-bit programmable counter array (PCA) with five capture/compare modules; (11)External Memory Interface (EMIF); (12)On-chip debug circuitry facilitates full speed, non-intrusive in-system debug (No emulator required); (13)Provides breakpoints, single stepping, inspect/modify memory and registers; (14)Superior performance to emulation systems using ICE-chips, target pods, and sockets.
