HD404849规格书详情
Description
The HD404849 series of HMCS400-series microcomputers is designed to increase program productivity and also incorporate large-capacity memory. Each microcomputer has an LCD controller/driver, A/D converter, input capture circuit, 32-kHz oscillator for clock use, and four low-power dissipation modes.
Features
• 35 I/O pins, including nine high-current pins (15 mA, max.), eight pins multiplexed with LCD segment pins, and four pins multiplexed with analog input pins
• Four timer/counters
• Eight-bit input capture circuit
• Three timer outputs (including two PWM outputs)
• Two event counter inputs (including one in which the detection edge is programmable)
• Clock-synchronous 8-bit serial interface
• A/D converter (8 channels × 8 bits)
- Operation voltage 2.7 V to 6.0 V
• LCD driver (32 segments × 4 commons)
• Built-in oscillators
- Main clock: Can be driven by ceramic oscillator, crystal oscillator, or external clock.
- Subclock: 32.768-kHz crystal
• Ten interrupt sources
- Four by external sources, including two in which the detection edge is programmable
- Six by internal sources
• Subroutine stack up to 16 levels, including interrupts
• Four low-power dissipation modes
- Standby mode
- Stop mode
- Watch mode
- Subactive mode
• One external input for transition from stop mode to active mode
• Instruction cycle time: 0.89 µs (fOSC = 4.5 MHz)
• Operation voltage
- VCC = 2.7 V to 6.0 V (subactive mode: 2.2 V to 6.0 V) (HD404848, HD404849)
- VCC = 2.7 V to 5.5 V (HD4074849)
• Two operating modes
- MCU mode (HD404848, HD4048412, HD404849)
- MCU/PROM mode (HD4074849 only)
