A cost effective solution to support USB to UART / USB to SPI applications.
Use a single crystal or resonator, with build-in capacitors from XI and XO to
ground, no external capacitors for the crystal or resonator is required. The
crystal or resonator can be either 6 MHZ or 12 MHZ, selected by a internal
option cell.
Built-in Sunplus 8 bit CPU core which can be running at up to 12 MHZ clock
rate.
Memory
10.5 K bytes Program (One-Time-Programmable) memory
192 bytes RAM
USB
Conforms to USB 2.0 Full speed specifications The crystal/resonator input is
connected to a built-in PLL to support the required clock rate for the USB
Support 5 end points; each endpoint can be programmed to be IN or OUT
endpoint.
I/O
12 general purpose I/O pins
Programmable I/O direction and pull-up /pull-down enable/disable selection
Parallel Interface with DMA
8-bit parallel interface with DMA controller allows the EP1 and EP2 buffer
can be accessed by external read/write command.
The max data rate of the parallel interface can be up to 1M byte/s
UART
Support Full-Duplex asynchronous serial communication. The max baud rate can
be up to 3 M bps with DMA control from the UART ports to USB.
10-bit or 11-bit mode with parity control
CRC generation
CRC16 or CRC-CCITT
Hardware CRC generation circuit
Timer
Timer0: 14-bit free-run timer, generates two interrupts: overflow IRQ
(T0_Flag) and real time IRQ (RTI).
Timer1: Re-loadable 8-bit timer, can be cascaded to 16-bit timer. It is used
exclusively by the UART when the UART is enabled.
Timer2: Re-loadable 8-bit timer, counting at USB frame rate 1 ms.
