Description

EM78P173NSO8J is an 8-bit microprocessor with low-power and high-speed CMOS technology. It features a 1K*13-bit Electrical One Time Programmable Read Only Memory (OTP-ROM) which allows for convenient program development and verification. Users can easily program their developed code using an EMC writer.

Specifications and features

- Operating voltage range: 2.2V~5.5V
- Temperature range: 0°C~70°C

- One configuration register to match the user’s requirements
- 48x8 bits on-chip registers (SRAM)
- 2 bi-directional I/O ports
- 5 level stacks for subroutine nesting
- 8-bit real-time clock/counter (TCC) with selective signal sources, trigger edges, and overflow interrupt
- Two clocks per instruction cycle
- Power-down mode (SLEEP mode)
- Three available interruptions: TCC overflow interrupt, Input-port status changed interrupt (wake up from the sleep mode), External interrupt
- Programmable free-running watchdog timer
- 8 pull-high pins
- 7 pull-down pins
- 8 open-drain pins
- Two R-option pins
- Package type: SOP, SOIC and DIP
- 99.9% single instruction cycle commands
