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.

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.

PIN DESCRIPTION
Table 1 Pin description
Pin
Vcc, Vss
Name
Power source
(Note 1)
Function
•Apply voltage of 2.2 to 5.5 V to Vcc, and 0 V to Vss.
Function expect a port function
VREF
Analog reference •Reference voltage input pin for A/D converter
voltage
CNVss
CNVss
•Chip operating mode control pin, which is always connected to Vss.
RESET
Reset input
•Reset input pin for active “L”
XIN
Clock input
•Input and output pins for main clock generating circuit
•Connect a ceramic resonator or quartz crystal oscillator between the XIN and XOUT pins.
XOUT
Clock output
•For using RC oscillator, short between the XIN and XOUT pins, and connect the capacitor and resistor.
•If an external clock is used, connect the clock source to the XIN pin and leave the XOUT pin open.
• When the on-chip oscillator is selected as the main clock, connect XIN pin to VSS and leave XOUT open.
P00/CNTR1
P01/TYOUT
P02/TZOUT
P03/TXOUT
P04–P07
I/O port P0
•8-bit I/O port.
•I/O direction register allows each pin to be individually pro-
grammed as either input or output.
•CMOS compatible input level
•CMOS 3-state output structure
• Key-input (key-on wake up
interrupt input) pins
• Timer Y, timer Z, timer X and
timer A function pin
•Whether a built-in pull-up resistor is to be used or not can be de-
termined by program.
P10/RxD1
P11/TxD1
I/O port P1
P12/SCLK1/SCLK2

• Input pins for A/D converter
(Note 2)
•CMOS compatible input level
•CMOS 3-state output structure
P30–P35
I/O port P3

•Whether a built-in pull-up resistor is to be used or not can be de- • Interrupt input pins
termined by program.
Notes 1: VCC = 2.4 to 5.5 V for the extended operating temperature version and the extended operating temperature 125 °C version.
2: P26/AN6 and P27/AN7 do not exist for the 32-pin version, so that Port P2 is a 6-bit I/O port.
3: P35 and P36/INT1 do not exist for the 32-pin version, so that Port P3 is a 6-bit I/O port.
