Description
The µPD6P8MC-5A4 is a microcontroller designed for infrared remote control transmitters. It is equipped with a one-time programmable memory for program storage. This feature allows users to write and evaluate programs for the microcontroller, making it ideal for program evaluation and small-scale production of application systems that utilize the µPD67A, 67B, 68A, 68B microcontrollers.Specifications and features
- Program memory (one-time PROM): 2026 × 10 bits - Data memory (RAM): 32 × 4 bits - On-chip carrier generator for infrared remote control: The high-level and low-level width can be set separately from 250 ns to 64 µs (@ fX = 4 MHz operation) via modulo registers - 9-bit programmable timer: 1 channel - Instruction execution time: 16 µs (@ fX = 4 MHz) - Stack level: 1 level (stack RAM is for data memory RF as well) - I/O pins (KI/O): 8 units - Input pins (KI): 4 units - Sense input pins (S0, S2): 2 units - S1/LED pin (I/O): 1 unit (when in output mode, this is the remote control transmission display pin) - Power supply voltage: VDD = 1.9 to 3.6 V - Operating ambient temperature: TA = –40 to +85°C - Oscillator frequency: fX = 3.5 to 4.5 MHz - On-chip POC circuit and RAM retention detector - On-chip oscillator (µPD6P8B)Application Scenarios
The µPD6P8MC-5A4 is commonly used in infrared remote control transmitters for AV and household electric appliances.Comparison
Advantages- One-time programmable memory for program storage - Wide range of settable high-level and low-level width for infrared remote control carrier generation - Programmable timer for precise timing control - Compact stack level and ample I/O pins for flexibility in system designDisadvantages- Limited data memory capacity compared to other microcontrollers -
