These devices are suitable for use in applications requiring high resolution A/D converter control, such as battery chargers. The HD404082 and HD404084 series offer less advanced features than the HD404384 series. They are 4- bit microcomputers that support low-voltage operation for backward software compatibility. HD404374 Series microcomputers have a 32.768 kHz sub-resonator for realtime clock use, providing a time counting facility, and a variety of low-power modes to reduce current drain. The HD407A4374, HD407A4384, HD407A4389, HD407C4374, HD407C4384, and HD407C4389 are ZTAT TM microcomputers with on-chip PROM that drastically shortens development time and ensures a smooth transition from debugging to mass production. (The PROM programming specifications are the same as for the 27256 type.) ZTAT TM: Zero Turn-Around Time. ZTATTM is a trademark of Renesas Technology Corp. Features • 20 I/O pins Large-current I/O pins (source: 10 mA max.):4 Large-current I/O pins (sink: 15 mA max.):4 Analog input multiplexed pins: 4 (HD404374, HD404384, and HD404389 Series) • 8-bit timer: 1 channel 16-bit timer: 1 channel (Can also be used as two 8-bit timer channels) • Two timer outputs (including PWM output) • Event counter inputs (edge-programmable) • Clock-synchronous 8-bit serial interface • A/D converter 4 channels × 10-bits (HD404374 and HD404384 Series) 6 channels × 10-bits (HD404389 Series) None (HD404082 and HD404084 Series) |
