The document describes the Hitachi HD64180R/Z, an 8-bit Micro Processing Unit (MPU) based on a microcoded execution unit and advanced CMOS manufacturing technology. It offers high performance, reduced system cost, and low power operation while maintaining compatibility with industry-standard 8-bit software.
Key hardware features include an integrated Memory Management Unit (MMU), two-channel Dual Mode Access Controller (DMAC), two-channel asynchronous serial communication interfaces, a clocked serial I/O port, and versatile interrupt controllers. The device supports operating frequencies up to 10 MHz and includes specific low-power operation modes.
| Operating Frequency | up to 10 MHz |
|---|---|
| Power Dissipation (Normal) | 25 mW at 10 MHz |
| Operating Temperature (Standard) | -20 ~ +75 °C |
| Storage Temperature | -55 to +160 °C |
| Memory Address Space (R/Z) | 512K bytes or 1M byte |
| Interrupts | Four external and eight internal |
The 'R' suffix indicates an interface with Motorola 68 and Intel 80xx peripherals, while 'Z' indicates an interface with Z80 peripherals.
The device supports an operating frequency of up to 10 MHz.
