RAMcapacity
– 1,024 × 8-bts (SM8504)
– 2,048 × 8-bts (SM8506)
Memory organization, it is possibetoset therangeof accessibe
address of theexternal memory in unit of 4K (4K to60K) by the
user program
External memory expansion, theSM8500 series can access
external memory by programsetting.
ARAMarea is usedas subroutinestack
CPUcore
– 8-bts × 8 ports (or 16-bts × 4 ports) and16-bts × 4 ports
general purposeregister areusedas accumulator register
ponter andindex register

– Systemclock cyclecan bevariedby program Systemclock
can bederivedfromthemain clock (dvidedby 1/2, 1/4, 1/8,
1/16 or 1/32) or sub-clock (dvided-by-2 32.768 kHz)
Built-in main-clock oscillator for systemclock
Built-in sub-clock oscillator for real timeclock
Interrupts

– 4 external interrupts and10 internal interrupts fromperi-
pheral functions can beset enabe/dsabeindependently
andmaskedby 14-leve priority
– 2 nonmaskabeinterrupts
– Watchdog timer interrupt, illegal instruction trap
Standby modes: Halt mode/Stopmode
I/Oports
– 16 Input (8 inputs alsousedas A/D input pns). Thepull-up
resistor of oneport (8-bts) can beturnedon/off by software
– 16 Output (largecurrent output pns)

– User programmabe16-leve waveforms, 32-step/1 period
waveformoutput
– Combnedwth external circuit, DTMF waveformcan be
output. Waveformgenerator can beusedby combning wth
D/Aconverter.
Clock output
– P7
6
/F pn can beusedtodrivea buzzer (timer 5 output)
Input capturefunction
Suppy votages
– 1.8 V to2.7 V (systemclock frequency; at 750 kHz MAX.)
– 2.7 V to3.6 V (systemclock frequency; at 3 MHz MAX.)
– 4.5 V to5.5 V (systemclock frequency; at 6 MHz MAX.)
– TheSM8500 series can operateat theMAX. 12 MHz main
clock if theoperating votageis in therange(2.7 to5.5 V).
However themain clock frequency must bedvidedtothe
systemclock accordng totheoperating votagerange

– 100-pn QFP (QFP100-P-1420)
DESCRIPTION
SM8504/SM8506 (SM8500) areCMOS 8-bt single-chipmcro-
computers containing SM85CPUcoreandtherequiredperipheral
functions for system SM85CPUis an 8-bt high performanceCPU
wth various addressing modes andhigh-efficiency instructions set.
SM85CPUis featuredby allocating general registers on RAMto
reduceoverheadwhen calling subroutines. Theperipheral func-
tions andmemory of SM8500 series contain ROM RAM timer/
counter serial interfaces (SIO UART), A/D converter D/A
converter andwaveformgenerator
