HD404639R Datasheet, PDF (4/135 Pages) Renesas Technology Corp – 4-Bit Single-Chip Microcomputer
HD404639R Series
• Comparator (4 channels)
• On-chip DTMF generator: fOSC = 400 kHz, 800 kHz, 2 MHz, 3.58 MHz, 4 MHz, 7.16 MHz, or 8 MHz
(7.16 MHz and 8 MHz are only available for HD40A4638R, HD40A4639R and HD407A4639R)
• Built-in oscillators
 Main clock: Ceramic oscillator or crystal (an external clock is also possible)
 Subclock: 32.768-kHz crystal
• Eleven interrupt sources
 Five by external sources, including three double-edge function
 Six by internal sources
• Subroutine stack up to 16 levels, including interrupts
• Four low-power dissipation modes
 Subactive mode
 Standby mode
 Watch mode
 Stop mode
• One external input for transition from stop mode to active mode
• Instruction cycle time: 1 µs (fOSC = 4 MHz at 1/4 division ratio), 0.5 µs (fOSC = 8 MHz at 1/4 division
ratio)
 1/4, 1/8, 1/16, or 1/32 division ratio can be selected
• Operation voltage
 2.7 V to 6.0 V (HD404638R, HD404639R, HD40A4638R, HD40A4639R)
 2.7 V to 5.5 V (HD407A4639R)
 With VCC = 2.2 V to 6.0 V, watch mode can be supported, and instructions can be executed in
subactive mode (not applicable to the HD407A4639R).
• Two operating modes
 MCU mode
 MCU/PROM mode (HD407A4639R)
