4 PERIPHERAL CIRCUITS

4 Peripheral Circuits

This chapter lists the built-in peripheral circuits and the I/O memory map. For details of the circuits, refer to the "S1C33210 FUNCTION PART".

4.1 List of Peripheral Circuits

The S1C33210 consists of the C33 Core Block, C33 Peripheral Block, C33 DMA Block and C33 Analog Block.

C33 Core Block

CPU

S1C33000 32-bit RISC type CPU

BCU (Bus Control Unit)

24-bit external address bus and 16-bit data bus

 

All the BCU functions can be used.

ITC (Interrupt Controller)

39 types of interrupts are available.

CLG (Clock Generator)

OSC3 oscillation circuit (33 MHz Max.), PLL and OSC1 oscillation circuit

 

(32.768 kHz Typ.) built-in

DBG (Debug Unit)

Functional block for debugging with the S5U1C33000H (In-Circuit Debugger

 

for S1C33 Family)

C33 Peripheral Block

Prescaler

Programmable clock generator for peripheral circuits

8-bit programmable timer

6 channels with clock output function

16-bit programmable timer

6 channels with event counter, clock output and watchdog timer functions

Serial interface

4 channels (asynchronous mode, clock synchronous mode and IrDA are

 

selectable. Interfaces 1 and 3 support only asynchronous operation.)

Input and I/O ports

7 bits of input ports and 27 bits of I/O ports (used for peripheral I/O)

Clock timer

1 channel with alarm function

Mobile access interfaces

One PHS, PDC, and HDLC interface each

C33 DMA Block

HSDMA (High-Speed DMA)

4 channels (Only two interfaces support external requests.)

IDMA (Intelligent DMA)

128 channels

C33 Analog Block

A/D converter

10-bit A/D converter with 4 input channels

A-14
