UPD753304 Description
The µPD753304 is one of the 75XL series 4-bit single-chip microcontroller chips and has a data processing capability parable to that of an 8-bit microcontroller. Since it inherits the 75X series CPU, it has upward patibility. While the conventional 75X series products with an on-chip LCD controller/driver use an 80-pin package, the µPD753304 is sold as a pellet/wafer to make it possible to be built into portable...
UPD753304 Key Features
- RC oscillation circuit on chip
- Main system clock: fCC = 3.6 MHz (typical value with 6.8-kΩ external resistor connected. An internal 10-pF (typ.) capaci
- Subsystem clock : fCT = 47 kHz (typ.) (Both a resistor and a capacitor are provided internally.)
- Processing can be started immediately after standby mode is released
- Oscillation of the subsystem clock can be stopped in STOP mode
- Supply voltage: VDD = 2.5 to 5.5 V
- On-chip memory
- Program memory (ROM) : 4096 × 8 bits
- Data memory (RAM) : 256 × 4 bits
- Variable instruction execution time function useful for power saving
