■ Low-Pin-Count (LPC) Interface
A popular interface to communicate to PC chip set
used in notebooks and PC servers
Performs serial data and address transfer using
33MHz clock
Supports I/O read and write cycles
Supports serial interrupt on single line
Supports power-down mode
Reduced pin count
■ Host Interface X-Bus Interface
Enables connection to the ISA (X-BUS)
Four channel parallel interface
Five host interrupt requests
■ Keyboard Buffer Controller (KBC)
Conforms to PS/2 specification
Error detection, parity error and stop bit monitoring
Five host interrupt requests
■ PC Break Controller (PBC)
Simplifies program debugging
Instruction and data compare
■ Dual-Tone Multi-Frequency
(DTMF) Generator
Generates DTMF frequency sine waveform,
with minimum distortion
Synthesis or single waveform
■ On-chip Bus Controller (BSC)
Provides glueless interface with external devices
Supports basic SRAM, burst-ROM interface
Manages external, addressable 16MB region
(8 different areas)
Bus specification can be set independently
for each region
Selectable 8- or 16-bit bus width
Choice of 0 to 7 programmable wait-state access
Supports direct connection to SDRAM
on selected devices
Includes a bus arbiter for bus mastership arbitration
Burst ROM interface can be set for area 0
External write cycle and internal access can be
executed in parallel
Idle-cycle insertion capability
