SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER
DESCRIPTION
The 7540 Group is the 8-bit microcomputer based on the 740 family
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 appliances
and office automation equipment.
FEATURES

The minimum instruction execution time .......................... 0.50 μs
(at 8 MHz oscillation frequency for the shortest instruction)
Memory size ROM ............................................16K to 32K bytes
RAM ..............................................512 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

Power dissipation ............................................ 25 mW (standard)
Operating temperature range ................................... –20 to 85 °C
(–40 to 85 °C for extended operating temperature version)
APPLICATION
Office automation equipment, factory automation equipment, home
electric appliances, consumer electronics, car, etc.
Note: 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.
