Voltage FLASH, 2 to 4 Kbytes RAM, 1K byte
emulated EEPROM (E3PROM^TM)
– 224 general purpose registers (register file)
available as RAM, accumulators or index
pointers
s Clock, Reset and Supply Management
PQFP100
– Register-oriented 8/16 bit CORE with RUN,
WFI, SLOW, HALT and STOP modes
– 0-24 MHz Operation (internal Clock), 4.5 - 5.5
Volt voltage range
– PLL Clock Generator (3-5 MHz crystal)
– Min. instruction time: 83 ns (24 MHz int.
clock)
s Interrupt Management
– 77 I/O pins
– 4 external fast interrupts + 1 NMI
– Up to 16 pins programmable as wake-up or
additional external interrupt with multi-level in-
terrupt handler
s Timers
– 16-bit Timer with 8 bit Prescaler, able to be
used as a Watchdog Timer with a large range
of service time (HW/SW enabling through
dedicated pin)
– 16-bit Standard Timer that can be used to
generate a time base independent of PLL
Clock Generator
s Communication Interfaces

ble Master/Slave mode
– J1850 Byte Level Protocol Decoder (JBLPD)
(on J versions only)
– Full I²C multiple Master/Slave Interface sup-
porting Access Bus
s 8-bit Analog to Digital Converter allowing up
to 16 input channels
s DMA Controller for reduced processor
overhead
s Instruction Set
– Rich Instruction Set with 14 Addressing
Modes
– Division-by-zero trap generation
s Development Tools
– Two 16-bit independent Extended Function
Timers (EFTs) with Prescaler, 2 Input Cap-
tures and two Output Compares
– Two 16-bit Multifunction Timers, with Prescal-
er, 2 Input Captures and 2 Output Compares
– Versatile Development Tools, including As-
sembler, Linker, C-Compiler, Archiver,
Source Level Debugger, Hardware Emulators
and Real Time Operating System
