Product details
Overview
DF38099FP10WV from Renesas Electronics is a 16-bit single-chip microcontroller in the H8/38099 Group, featuring the H8/300H CPU core with instruction set compatibility to H8/300. It operates at up to 20 MHz, integrates 128 KB on-chip ROM and 8 KB RAM, supports 5 V operation, and includes on-chip peripherals such as UART (SCI), timer modules, and I/O ports - used in industrial control panels requiring deterministic real-time response.
For engineers reviewing the DF38099FP10WV datasheet, DF38099FP10WV pinout, DF38099FP10WV application, or DF38099FP10WV equivalent, key selection considerations include its 100-pin LQFP package, 5 V supply tolerance, ROM-based firmware execution, SCI serial interface configuration, and H8/300H instruction compatibility for legacy code migration.
Technical Context
The DF38099FP10WV implements the H8/300H CPU architecture with 24-bit addressing, supporting both little-endian data format and 16-bit general-purpose registers. Its clock system accepts external crystal (1–20 MHz), ceramic resonator, or external clock input, with internal PLL options enabling stable high-speed operation.
Interrupt handling uses a priority-based controller with 6-level nesting, supporting 32 interrupt sources including external pins, on-chip timers, and serial communication events. Memory mapping reserves dedicated areas for ROM (0x000000–0x01FFFF), RAM (0xFFE000–0xFFFFFF), and peripheral registers (0xFFC000–0xFFDFFF).

FAQ
What is the maximum operating frequency of the DF38099FP10WV?
The DF38099FP10WV supports a maximum operating frequency of 20 MHz when using an external crystal or clock source. This frequency is achieved via the on-chip clock pulse generator with internal dividers and PLL options. At 20 MHz, the DF38099FP10WV delivers consistent 50 ns instruction cycle timing critical for hard real-time loop execution in industrial control applications.
Does the DF38099FP10WV include on-chip debug capabilities?
Yes, the DF38099FP10WV supports on-chip debugging via the E8 emulator interface. Pins NMI, P16, P36, and P37 are reserved for this purpose, enabling non-intrusive breakpoints, register inspection, and memory read/write during development. The DF38099FP10WV hardware manual specifies strict usage constraints - such as prohibiting access to memory ranges H'020000–H'020FFF - to ensure reliable emulator operation.
What power supply voltage range does the DF38099FP10WV require?
The DF38099FP10WV operates from 4.5 V to 5.5 V DC, making it compatible with standard 5 V industrial power supplies. This voltage range ensures stable operation under typical line ripple and transient conditions found in factory environments. The DF38099FP10WV's "Standard" quality grade confirms suitability for industrial equipment where 5 V rail stability is maintained through local regulation.
How many serial communication interfaces does the DF38099FP10WV integrate?
The DF38099FP10WV integrates three independent Serial Communication Interface (SCI) modules, each configurable as UART. These support full-duplex asynchronous communication at baud rates up to 1 Mbps, with built-in noise filtering and framing error detection. In DF38099FP10WV-based systems, SCI channels commonly serve host connectivity, debug logging, and peripheral bridging simultaneously.
Is the DF38099FP10WV pin-compatible with other H8/38099 variants?
No - the DF38099FP10WV is not pin-compatible with other H8/38099 variants such as the DF38099FP8WV (80-pin) or DF38099FP12WV (128-pin). While all share the same H8/300H core and peripheral set, the DF38099FP10WV specifically uses a 100-pin LQFP package with defined pin assignments for VCC, GND, I/O, and peripheral signals. Substituting packages requires PCB layout revision and signal routing validation.
