This is a user manual about µPD78F9510, 78F9511, 78F9512 8-bit Single-Chip Microcontrollers
This manual is intended for engineers who need to understand the functions of the µPD78F9510, µPD78F9511, and µPD78F9512 microcontrollers in order to design and develop application systems. It covers pin functions, internal block functions, CPU architecture, instruction set, and electrical specifications.
Key sections include pin configuration tables, CPU block diagrams, clock generator settings, timer/event counter operation, and detailed electrical ratings such as supply voltage, input/output voltage ranges, and current limits. The document also contains cautions, handling instructions, and references to related development tools.
| Supply voltage (VDD) | −0.3 V to +6.5 V |
|---|---|
| Input voltage (VSS) | −0.3 V to +0.3 V |
| Output current, high per pin (I OH) | −10 mA |
| Operating ambient temperature (TA) during flash programming | −40 °C to +85 °C |
Each unused pin should be connected to VDD or GND via a resistor to prevent floating inputs that could cause malfunction.
When turning the device off, switch off the external power supply first and then the internal power supply; the reverse order is used when powering on.
The device operates with a supply voltage (VDD) from –0.3 V up to +6.5 V.
