Pin No.

Pin name

I/O

Function

Classification

Microcomputer

interface

Microcomputer interface writes request pin.

RQ =”L”: Microcomputer interface enable.

Microcomputer interface serial data clock pin.

When SCLK does not use, leave SCLK=”H”.

SCLK

Microcomputer interface serial data input and serial data output control pin.

When SI does not use, leave SI=”L”.

DVSS

DVDD

Power supply

Ground pin for digital section.

Power supply pin for digital section 5V or 3.3V (typ)

Serial data output pin for Microcomputer interfaces.

Microcomputer

interface

Data write ready output pin for Microcomputer interface.

RDY

DRDY

LSEL

Output data ready pin for Microcomputer interface.

Input level selector pin.

Level select

When using 5.0V power supply, the level of this pin decides input pin level.

When this pin level is “H”, then TTL level input is available.

When using 3.3V power supply, this pin must leave open or connects to DVSS.

External RAM Inteface

CAS

RAS

CAS Pin for external DRAM.

RAS pin for external DRAM

Writes enable pin for external SRAM/DRAM.

Address output for external RAM (A0~A4)

A0 ~ A4

DVSS

DVDD

Power supply

Ground pin for digital section 0V.

Power supply pin for digital section 5V or 3.3V (typ)

Address output for external RAM (A5~A16 )

External RAM

Interface

A5 ~ A16

DVSS

DVDD

Power supply

Ground pin for digital section 0V.

Power supply pin for digital section 5V or 3.3V (typ)

Output enable signal output for external SRAM/DRAM.

External RAM

Interface

Data input / output for external SRAM / DRAM.

I/O These pins work as output pin unless READ data from external RAM instruction.

If it does not connect external RAM then leave open.

IO0 ~ IO7
