Product details
Overview
HD6473278CQ10XL from Renesas (formerly Hitachi) is a 16-bit single-chip microcontroller in the H8/327 series, featuring an H8/300 CPU core, 16 KB on-chip masked ROM, 512-byte RAM, one 16-bit free-running timer, two 8-bit timers, an 8-channel 10-bit A/D converter, and a serial communication interface (SCI). It operates at up to 10 MHz and targets embedded control systems such as industrial sensors and motor controllers.
For engineers reviewing the HD6473278CQ10XL datasheet, HD6473278CQ10XL pinout, HD6473278CQ10XL application, or HD6473278CQ10XL equivalent, key selection criteria include ROM size (16 KB), RAM capacity (512 B), A/D resolution (10-bit, 8-channel), SCI support, and QFP-100 package compatibility for space-constrained industrial PCBs.
Technical Context
The HD6473278CQ10XL implements the H8/300 CPU core with two-way general register architecture (eight 16-bit or sixteen 8-bit registers), supporting 2- and 4-byte instructions and bit-manipulation operations optimized for real-time control. It executes ADD/SUB in 0.2 µs and MUL/DIV in 1.4 µs at 10 MHz.
It supports three operating modes - single-chip mode (Mode 3) and two expanded modes (Modes 1 and 2) - selected via external pins and controlled by SYSCR (H'FFC4) and MDCR (H'FFC5). Power management includes Sleep, Software Standby, and Hardware Standby modes with configurable wake-up sources.
