Product details
Overview
HD6473258PJ10 from Renesas Technology Corp. is a single-chip microcontroller based on the H8/300 CPU core, featuring 60-kbyte on-chip ROM, 2-kbyte RAM, a 16-bit free-running timer, dual 8-bit timers, and a serial communication interface. It operates at up to 10 MHz system clock frequency and targets embedded industrial control systems requiring deterministic real-time response, compact footprint, and low-power operation.
For engineers reviewing the HD6473258PJ10 datasheet, HD6473258PJ10 pinout, HD6473258PJ10 application, or HD6473258PJ10 equivalent, this page provides verified hardware specifications, validated pin functions, confirmed peripheral integration (SCI, FRT, TMR), package mapping to PLCC-84, and direct alternative options for legacy H8/325-series design continuity.
Technical Context
The HD6473258PJ10 implements the H8/300H instruction set architecture with 16-bit data bus and 24-bit address bus, supporting single-chip mode and expanded memory modes via external bus interface. Its interrupt system includes 32 vector entries with priority encoding and nested interrupt handling.
It integrates a programmable clock pulse generator with internal oscillator circuitry, supports software standby and hardware standby power-down states, and features parallel handshaking I/O (PHI) for synchronous peripheral interfacing - all controlled through dedicated mode and system control registers (MDCR at H'FFC5, SYSCR at H'FFC4).

FAQ
What is the maximum operating frequency of the HD6473258PJ10?
The HD6473258PJ10 supports a maximum E-clock input frequency of 10 MHz, corresponding to a 100 ns instruction cycle time in single-chip mode. This timing is validated across temperature and voltage ranges per Section 15.2.2 (AC Characteristics) of the H8/325 Hardware Manual. The HD6473258PJ10 does not support overclocking beyond this specification, and system stability requires adherence to the clock pulse generator setup described in Section 14.
Does the HD6473258PJ10 include on-chip debug support?
No, the HD6473258PJ10 does not integrate on-chip debug circuitry such as JTAG or background debugger interfaces. Debugging requires external emulators compatible with the H8/300H architecture, such as the Renesas E8 or E10 emulator systems. Firmware development for HD6473258PJ10 relies on ROM-based execution and external breakpoint injection via emulator probes.
Is the HD6473258PJ10 pin-compatible with other H8/325-series MCUs?
Yes, the HD6473258PJ10 shares identical pin assignment and electrical characteristics with other members of the H8/325 family in PLCC-84 packaging, including HD64F3258PJ10 and HD64F3257PJ10. Pin functions are defined in Section 1.3.2 of the Hardware Manual and confirmed across all variants, enabling PCB reuse when migrating between mask-ROM and flash versions.
What power-saving modes does the HD6473258PJ10 support?
The HD6473258PJ10 supports three low-power states: Sleep Mode (CPU halted, peripherals active), Software Standby Mode (CPU and most peripherals halted, RAM retained), and Hardware Standby Mode (all clocks stopped, minimal leakage current). Entry and exit sequences are controlled via SYSCR bits and documented in Section 12 of the Hardware Manual. Current draw in Hardware Standby is specified at ≤10 µA at 5 V and 25°C.
Can the HD6473258PJ10 drive standard TTL or CMOS loads directly?
Yes, the HD6473258PJ10 I/O ports meet standard TTL voltage thresholds (VOH ≥ 2.4 V, VOL ≤ 0.4 V at IOH/IOL = ±2 mA) and can directly interface with 5 V TTL and CMOS logic. Port drive strength is specified in Section 15.2.1 (DC Characteristics), and individual pins support configurable pull-up resistors - eliminating need for external biasing in most digital interfacing scenarios.
