UPSD3315B-40U6 数据手册

µPSD3200 FAMILY

SUMMARY DESCRIPTION

■ Dual bank Flash memories

– One 16-bit PWM unit

– Concurrent operation, read from memory one

while erasing and writing the other. In-Appli-

cation Programming(IAP) for remote updates

■ Standalone Display Data Channel (DDC)

– For use in monitor, projector, and TV applica-

tions

– Large 128 KByte or 256 KByte main Flash

memory for application code, operating sys-

tems, or bit maps for graphic user interfaces

– Compliant with VESA standards DDC1 and

DDC2B

– Eliminate external DDC PROM

– Large 32 KByte secondary Flash memory di-

vided in small sectors. Eliminate external EE-

PROM with software EEPROM emulation

■ Six I/O ports with up to 50 I/O pins

– Multifunction I/O: GPIO, DDC, I C, PWM,

PLD I/O, supervisor, and JTAG

– Secondary Flash memory is large enough for

sophisticated communication protocol (USB)

during IAP while continuing critical system

tasks

– Eliminates need for external latches and logic

■ 3000 gate PLD with 16 macrocells

– Create glue logic, state machines, delays,

etc.

■ Large SRAM with battery back-up option

– Eliminate external PALs, PLDs, and 74HCxx

– Simple PSDsoft Express software ...Free

■ Supervisor functions

– 8 KByte SRAM for RTOS, high-level languag-

es, communication buffers, and stacks

■ Programmable Decode PLD for flexibleaddress

mapping of all memories

– Generates reset upon low voltage or watch-

dog time-out. Eliminate external supervisor

device

– Place individual Flash and SRAM sectors on

any address boundary

– Built-in page register breaks restrictive 8032

limit of 64 KByte address space

– Reset In pin

■ In-System Programming (ISP) via JTAG

– Special register swaps Flash memory seg-

ments between 8032 “program” space and

“data” space for efficient In-Application Pro-

gramming

– Program entire chip in 10 - 25 seconds with

no involvement of 8032

– Allows efficient manufacturing, easy product

testing, and Just-In-Time inventory

■ High-speed clock standard 8032 core (12-cycle)

– Eliminate sockets and pre-programmed parts

– Program with FlashLINK^TMcable and any PC

■ Content Security

– 40 MHz operation at 5 V, 24 MHz at 3.3 V

– Two UARTs with independent baud rate,

three 16-bit Timer/Counters and two External

Interrupts

– Programmable Security Bit blocks access of

device programmers and readers

■ USB Interface (µPSD3234A-40U6 only)

■ Zero-Power Technology

– Supports USB 1.1 Slow Mode (1.5 Mbit/s)

– Memories and PLD automatically reach

standby current between input changes

– Control endpoint 0 and interrupt endpoints 1

and 2

■ Packages

■ I C interface for peripheral connections

– 52-pin TQFP

– Capable of master or slave operation

■ Five Pulse Width Modulator (PWM) channels

– Four 8-bit PWM units

– 80-pin TQFP: allows access to 8032 address/

data/control signals for connecting to external

peripherals
