DESCRIPTION
The 7542 Group is the 8-bit microcomputer based on the 740 fam-
ily core technology.
The 7542 Group has serial interfaces, 8-bit timers, 16-bit timers,
and an A/D converter, and is useful for control of home electric ap-
pliances and office automation equipment.

The minimum instruction execution time ............................. 0.25 µs
(at 8 MHz oscillation frequency, double-speed mode for the
shortest instruction)
Memory size

Interrupts ................................................. 18 sources, 16 vectors
Timers ............................................................................. 8-bit 2
...................................................................................... 16-bit 2
• Output compare ............................................................ 4-channel
• Input capture ................................................................ 2-channel
Serial interface ............ 8-bit 2 (UART or Clock-synchronized)
A/D converter ............................................... 10-bit 8 channels
(6 channels in 32-pin version and PWQN0036KA-A package
version)
Clock generating circuit ............................................. Built-in type
(low-power dissipation by an on-chip oscillator)
(connected 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 double-speed mode
At 8 MHz .................................................................... 4.5 to 5.5 V
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 in high-speed mode or
middle-speed mode
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 ................................................ 27.5 mW (Typ.)
