Winbond 

Features (Continued)

■ Two SMBus (SMB) Interface Modules; each module:

— Is Intel SMBus, Philips I2C® and ACCESS.bus

compatible

— Is SMBus master and slave

— Supports up to two simultaneous slave addresses

— Supports polling- and interrupt-controlled operations

— Generates a wake-up signal on detection of a Start

condition while in Idle mode

— Supports an optional internal pull-up on SDA and

SCL pins

■ Core Universal Asynchronous Receiver-Transmitter

(CR_UART) Module

— A full-duplex UART channel

— Programmable baud rate

— Data transfer via interrupt or polling

■ Two 16-bit Multi-Function Timer (MFT16) Modules;

each module has:

— Two 16-bit timers with a 5-bit prescaler

— Pulse Width Modulation (PWM), Capture and

Timer/Counter modes

— Capture inputs with programmable edge detection

— An interrupt on compare match

■ Two Pulse Width Modulation (PWM) Modules

— Group A_PWM: two outputs

— Group B_PWM: one output

■ Serial Peripheral Interface (SPI) Module

— Bus master

— 8-bit interface

— Up to 10 MHz data clock rate

— Clock can be selected to be high or low in Idle mode

— Clock polarity can be selected for normal (sample on

rising edge) or alternate (sample on falling edge)

■ Timer and Watchdog (TWD)

— 16-bit periodic interrupt timer with 30 µs resolution

and 5-bit prescaler for system tick and periodic

wake-up tasks

— 8-bit watchdog timer with enable/disable

— “Watchdog occurred” flag

— Two watchdog reset options: warm or cold

■ SensorPath™ Bus Interface

— Single Wire bus master

— Supports up to seven slave devices

— x1, x4 SensorPath clock rate support

■ Analog-to-Digital Converter (ADC)

— Six channels, with 8-bit resolution

— 125 µs conversion time

— External voltage reference

■ Digital-to-Analog Converter (DAC)

— Four channels, 8-bit resolution

— 1 µs conversion time for 50 pF load

— Full output range from AGND to AVCC

■ Development Support

— Interface to debugger via Nexus 5001 interface

❏ Physical connection using JTAG

❏ On-board Debug mode with eight hardware

breakpoints

❏ Embedded memory programing via JTAG with

content read protection

■ Core Access to Host Modules

— Enabled via lock mechanism

Host Function Features

NEC, RCA and RECS 80

■ Fast Infrared (FIR) Port (WPC8768L only)

— Software compatible with the 16550A and the 16450

— Shadow register support for write-only bit monitoring

— FIR IrDA 1.1 compliant

— HP-SIR

— ASK-IR option of SHARP-IR

— DASK-IR option of SHARP-IR

— Consumer Remote Control supports RC-5, RC-6,

NEC, RCA and RECS 80

— DMA support: one or two channels

■ Serial Port (SP)

— In the WPC8768L, SP can be used only when FIR is

not needed

— Software compatible with the 16550A and the 16450

— Shadow register support for write-only bit monitoring

— UART data rates up to 1.5 Mbaud

■ Supports Microsoft® Advanced Power Management

(APM) Specifications Revision 1.2, February 1996

— Generates the System Management Interrupt (SMI)

■ PC01 Rev 1.0 and ACPI 3.0 Compliant

— PnP configuration register structure

— Flexible resource allocation for all logical devices

❏ Relocatable base address

❏ 15 IRQ routing options

❏ Four optional 8-bit DMA channels (where applicable)
