HD6417032F20V

Product Summary

The HD6417032F20V is a 32-Bit RISC Microcomputer. It comprises a new generation of reduced instruction set computers (RISC) in which a Hitachi-original CPU and the peripheral functions required for system configuration are integrated onto a single chip. The HD6417032F20V has a RISC-type instruction set. Most instructions can be executed in one system clock cycle, which strikingly improves instruction execution speed. In addition, the HD6417032F20V has a 32-bit internal architecture for enhanced data-processing ability. As a result, the HD6417032F20V enables high-performance systems to be constructed with advanced functionality at low cost, even in applications such as realtime control that require very high speeds, an impossibility with conventional microcomputers.

Parametrics

HD6417032F20V absolute maximum ratings: (1)Power supply voltage, VCC: -0.3 to +7.0 V; (2)Program voltage, VPP: -0.3 to +13.5 V; (3)Input voltage (except port C), Vin: -0.3 to VCC + 0.3 V; (4)Input voltage (port C), Vin: -0.3 to AVCC + 0.3 V; (5)Analog power supply voltage, AVCC: -0.3 to +7.0 V; (6)Analog reference voltage, AVref: -0.3 to AVCC + 0.3 V; (7)Analog input voltage, VAN: -0.3 to AVCC + 0.3 V; (8)Operating temperature, Topr: -20 to +75℃; (9)Storage temperature, Tstg: -55 to +125℃.

Features

HD6417032F20V features: (1)16 settable priority levels: Five interrupt priority registers can set 16 levels of interrupt priorities for IRQ and on-chip supporting module interrupt sources; (2)NMI noise canceller function: INTC has an NMI input level bit that indicates the NMI pin status. By reading this bit in the interrupt exception handling routine, the pin status can be checked for use in a noise canceller function; (3)The interrupt controller can notify external devices (via the IRQOUT pin) that an on-chip interrupt has occurred. In this way an external device can, for example, be informed if an on-chip interrupt occurs while the chip is operating in bus-released mode and the bus has been requested.
