7540 Group
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
• ^{Basic machine-language instructions ....................................... 71}
• ^{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 ! 4}
16-bit ! 1
• ^{Serial I/O1 ...................................................................... 8-bit ! 1}
(UART or Clock-synchronized)
• ^{Serial I/O2 ...................................................................... 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 oscillator
permitting RC oscillation)
• ^{Watchdog timer ............................................................ 16-bit ! 1}
• ^{Power source voltage}
XIN oscillation frequency at ceramic oscillation, in high-speed mode
At 8 MHz .................................................................... 4.0 to 5.5 V
At 4 MHz .................................................................... 2.4 to 5.5 V
At 2 MHz .................................................................... 2.2 to 5.5 V
XIN oscillation frequency at RC oscillation
At 4 MHz .................................................................... 4.0 to 5.5 V
At 2 MHz .................................................................... 2.4 to 5.5 V
At 1 MHz .................................................................... 2.2 to 5.5 V
• ^{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.
