IrDA FIR/VFIR Controller in TFBGA Package

Data Sheet

Description

Features

General Features

• Interfaces with IrDA Compliant IR Transceiver

up to VFIR

• Miniature 48 pin TFBGA Package

Height : 1.2 mm

The ASDL-7021 is a new generation large scale integra-

tion (LSI) IrDA controller supporting speeds of SIR (up

to 115Kbps), MIR(1.152Mbps), FIR(4Mbps) and VFIR

(16Mbps). It consists of IrDA Control Block, Remote

Control Block, Timer Control Block, Global Control block

including Buﬀer Memory and Direct Memory Access

Control Block (DMA) integrated into one single chip.

Width : 4.0 mm

Depth : 4.0 mm

It has all the hardware including Buﬀer Memory and

Direct Memory Access (DMA) that enables convenient

access to its peripheral IO and memories from system bus

which is similar to simple memory devices. ASDL-7021 is

a class of its own as unlike conventional LSI which utilizes

external DMA for implementing fast infrared transfer,

complicated bus timing and required additional logic for

its interface.

• 8-bit Memory Mapped Interface

• Input clock of 48 MHz

• 4 transmission speed in 3 Blocks

SIR Block (2.4 to 115.2Kbps)

FIR Block (1.152Mbps for MIR and 4Mbps for FIR)

VFIR Block (16Mbps)

• Operating temperature from -40° C ~ 85°C

Critical parameters are guaranteed over

temperature and supply voltage

ASDL-7021 utilizes two memory banks for external access

and internal DMA access; these 2 banks are interchange-

able to prevent bus contention. These two banks can be

switched using memory select function of the internal

enables parallel operation of external microcontroller

operation and internal IrDA data transfer operation.

ASDL-7021 has embedded Universal Remote Control (RC)

function for general purpose remote control communica-

tion.

• Core Power Supply = 1.8V

Clock Power Supply = 3.3V

IO Power Supply =1.8V, 2.5V, 3.3V

• RAM Block with On-Chip buﬀer memory of 8KByte x 2

Bank Conﬁguration

1 bank for external access x 8 bit width

1 bank for internal access x 8 bit width through

on-chip DMA block

These 2 banks can be switched

Each transmit and receive have their own buﬀer

memory of 8KByte x 2

Together with Lite-On FIR transceiver and IrSimple

software, ASDL-7021 is designed to provide Industry

a total solution for high speed wireless connectivity

solution in miniature packaging.
