7540 Group SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER REJ03B0011-0400 Rev.4.00 Jun 21, 2004 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 ......................... 0.34 µs (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 an on-chip 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 double-speed mode At 6 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 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 version (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.
