SUMMARY DESCRIPTION
I
Dual bank Flash memories
– Concurrent operation, read from memory
while erasing and writing the other. In-Appli-
cation Programming (IAP) for remote updates
– Large 128KByte or 256KByte main Flash
memory for application code, operating sys-
tems, or bit maps for graphic user interfaces
– Large 32KByte secondary Flash memory di-
vided in small sectors. Eliminate external EE-
PROM with software EEPROM emulation
– Secondary Flash memory is large enough for
sophisticated communication protocol (USB)
during IAP while continuing critical system
tasks
I
Large SRAM with battery back-up option
– 32KByte SRAM for RTOS, high-level lan-
guages, communication buffers, and stacks
I
Programmable Decode PLD for flexible address
mapping of all memories
– Place individual Flash and SRAM sectors on
any address boundary
– Built-in page register breaks restrictive 8032
limit of 64KByte address space
– Special register swaps Flash memory seg-
ments between 8032 “program” space and
“data” space for efficient In-Application Pro-
gramming
I
High-speed clock standard 8032 core (12-cycle)
– 40MHz operation at 5V, 24MHz at 3.3V
– 2 UARTs with independent baud rate, three
16-bit Timer/Counters and two External Inter-
rupts
I
USB Interface (some devices only)
– Supports USB 1.1 Slow Mode (1.5Mbit/s)
– Control endpoint 0 and interrupt endpoints 1
and 2
I
I
2
C interface for peripheral connections
– Capable of master or slave operation
I
5 Pulse Width Modulator (PWM) channels
– Four 8-bit PWM units
– One 8-bit PWM unit with programmable peri-
od
I
4-channel, 8-bit Analog-to-Digital Converter
(ADC) with analog supply voltage (V
REF
)
I
Standalone Display Data Channel (DDC)
– For use in monitor, projector, and TV applica-
tions
– Compliant with VESA standards DDC1 and
DDC2B
– Eliminate external DDC PROM
I
Six I/O ports with up to 50 I/O pins
– Multifunction I/O: GPIO, DDC, I
2
C, PWM,
PLD I/O, supervisor, and JTAG
– Eliminates need for external latches and logic
I
3000 gate PLD with 16 macrocells
– Create glue logic, state machines, delays,
etc.
– Eliminate external PALs, PLDs, and 74HCxx
– Simple PSDsoft Express software ...Free
I
Supervisor functions
– Generates reset upon low voltage or watch-
dog time-out. Eliminate external supervisor
device
– RESET Input pin; Reset output via PLD
I
In-System Programming (ISP) via JTAG
– Program entire chip in 10 - 25 seconds with
no involvement of 8032
– Allows efficient manufacturing, easy product
testing, and Just-In-Time inventory
– Eliminate sockets and pre-programmed parts
– Program with FlashLINK
TM
cable and any PC
I
Content Security
– Programmable Security Bit blocks access of
device programmers and readers
I
Zero-Power Technology
– Memories and PLD automatically reach
standby current between input changes
I
Packages
– 52-pin TQFP
– 80-pin TQFP: allows access to 8032 address/
data/control signals for connecting to external
peripherals
