FUNCTIONAL DESCRIPTION
CL-PS7111
Low-Power System-on-a-Chip
3.1
Main Functional Blocks
The CL-PS7111 is built around the ARM710a processor core. For a more detailed description of the
ARM710a, refer to the ARM710a Macrocell Data Sheet (http://www.arm.com/).
The main functional blocks in CL-PS7111 are:
G
ARM7 CPU core
G
8 Kbytes of unified instruction and data cache, a four-way set-associative
G
Memory management unit (MMU)
G
Two 16-bit general-purpose counters
G
A 32-bit realtime clock and comparator
G
On-chip boot ROM programmed with serial boot load sequence
G
Advanced system state control and power management
G
Direct interface to two CL-PS6700 PCMCIA controllers
G
Expansion and ROM interface for four, five, or six 256-Mbyte expansion segments with independent wait
state control
G
DRAM controller supporting Fast Page mode, self-refresh in Standby mode, and both 16-bit and 32-bit-wide
memory
G
Programmable LCD controller with 1-, 4-, or 16-level grayscaler
G
2 Kbytes of SRAM for a small LCD frame buffer
G
IrDA SIR protocol controller, capable of speeds up to 115.2 kbps
G
Two full-duplex 16C550 style UARTs with two 16-byte FIFOs
G
Main oscillator with PLL (phase locked loop) to generate the system clock of 18.432 MHz from a 3.6864-MHz
crystal
G
Optional external 13-MHz clock input
G
A low-power 32.768-kHz oscillator
G
Interrupt and fast interrupt controller
G
27 bits of general-purpose I/Os
G
Two DC-to-DC converter interfaces
G
One synchronous serial interface for Microwire
or SPI
peripherals (such as ADCs)
G
Telephony codec interface with 16-byte FIFOs for transmit and receive
G
Programmable frame buffer start address, allowing a system to be built using only external or internal SRAMs
for memory, eliminating any need for DRAMs
G
Pin test and device-isolation test logic
G
External tracing support for debug
