DESCRIPTION
The 7540 Group is the 8-bit microcomputer based on the 740 fam-
ily core technology.
The 7540 Group has a serial I/O, 8-bit timers, a 16-bit timer, and
an A-D converter, and is useful for control of home electric appli-
ances and office automation equipment.
FEATURES
Basic machine-language instructions ...................................... 71
The minimum instruction execution time ......................... 0.34
s
(at 6 MHz oscillation frequency, double-speed mode for the
shortest instruction)
Memory size ROM ............................................ 8 K to 32 K bytes
RAM ............................................. 384 to 768 bytes
Programmable I/O ports ....................... 29 (25 in 32-pin version)
Interrupts ................................................. 15 sources, 15 vectors
................................. (14 sources, 14 vectors for 32-pin version)
Timers ............................................................................. 8-bit
4
...................................................................................... 16-bit
1
Serial I/O1 ................... 8-bit
1 (UART or Clock-synchronized)
Serial I/O2 (Note 1) ..................... 8-bit
1
(Clock-synchronized)
A-D converter ............................................... 10-bit
8 channels
.................................................... (6 channels for 32-pin version)
Clock generating circuit ............................................. Built-in type
(low-power dissipation by a ring oscillator enabled)
(connect to external ceramic resonator or quartz-crystal oscilla-
tor permitting RC oscillation)
Watchdog timer ............................................................ 16-bit

At 1 MHz .................................................................... 2.2 to 5.5 V
Power dissipation
Mask ROM version ....................................... 22.5 mW (standard)
One Time PROM version ................................ 30 mW (standard)
Operating temperature range ................................... 20 to 85 C
(40 to 85 C for extended operating temperature version)
(40 to 125 C for extended operating temperature 125 C ver-
sion (Note 2))
APPLICATION
Office automation equipment, factory automation equipment,
home electric appliances, consumer electronics, car, etc.
Notes 1: Serial I/O2 can be used in the following cases;
(1) Serial I/O1 is not used,
(2) Serial I/O1 is used as UART and BRG output divided by 16 is
selected as the synchronized clock.
2: In this version, the operating temperature range and total time
are limited as follows;
55 C to 85 C: within total 6000 hours,
85 C to 125 C: within total 1000 hours.
PRELIMINARY
