The 82C59A from Toshiba is a CMOS Priority Interrupt Controller built using an advanced 2µm CMOS process. It is designed to offload the system CPU from polling tasks in multilevel priority systems. This controller is compatible with various microprocessors including 80C286, 80286, 80C86/88, 8086/88, 8080/85, and NSC800.
The 82C59A can manage up to eight vectored priority interrupting sources and can be cascaded to support up to 64 interrupt levels without additional circuitry. Individual interrupt sources can be masked or prioritized for custom system configurations. It offers two modes of operation, making it compatible with both 8080/85 and 80C86/88/286 formats.
Featuring a static CMOS design, the 82C59A ensures low operating power with a typical standby current of 10 µA and an operating current of 1 mA/MHz. It operates from a single 5V power supply and is available in versions supporting 5MHz, 8MHz, and 12.5MHz operation. The device is pin-compatible with the NMOS 8259A and is available in PDIP and PLCC packages, with commercial, industrial, and military temperature ranges supported.
