Product details
Overview
HD6477042ACFI28V from Renesas is a 32-bit RISC microcontroller based on the SH-2 CPU core, featuring 128 kB on-chip mask ROM, 16-bit external bus width, ±4 LSB A/D conversion accuracy (mid-speed mode), and operation at 28 MHz/5 V. It integrates timers, SCI, DMA, A/D converter, and I/O ports for embedded real-time control in industrial automation systems.
For engineers reviewing the HD6477042ACFI28V datasheet, HD6477042ACFI28V pinout, HD6477042ACFI28V application, or HD6477042ACFI28V equivalent, key selection criteria include its QFP2020-112 package, SH-2 instruction set compatibility, 128 kB mask ROM configuration, 5 V supply requirement, and support for external memory expansion via 16-bit data bus.
Technical Context
The HD6477042ACFI28V implements the SuperH RISC engine SH-2 core with single-cycle instruction execution for high throughput in deterministic real-time tasks. Its 32-bit internal bus architecture enables efficient data movement between on-chip peripherals including dual-channel SCI, 8-channel DMA, and 8-channel 10-bit A/D converter.
It supports multiple operating modes-user, user program, and standby-with hardware-assisted flash programming (F-ZTAT variant) and configurable pin functions via Pin Function Controller (PFC). The device uses asynchronous interrupt inputs (IRQ0–IRQ7, NMI) with clock-edge-synchronized recognition when setup times are met.
