Overview

DF38099FP10V from Renesas Electronics is a 16-bit single-chip microcontroller in the H8/300H Super Low Power Series, featuring an H8/300H CPU core with H8/300 instruction set compatibility, 128 KB on-chip ROM, 8 KB RAM, and integrated peripherals including 3-channel UART (SCI), 16-bit timer/counters, and 8-channel 10-bit ADC. It operates at up to 20 MHz with supply voltage range 2.7–5.5 V and targets battery-powered industrial control and sensor interface applications.

For engineers reviewing the DF38099FP10V datasheet, DF38099FP10V pinout, DF38099FP10V application, or DF38099FP10V equivalent, key selection criteria include its low-power active/standby modes, on-chip debug support via E8 interface, 10-bit ADC resolution with sample-and-hold, SCI channel configuration flexibility, and qualification for Standard-grade industrial use per Renesas quality classification.

Technical Context

The DF38099FP10V implements the H8/300H CPU architecture with 24-bit address space, supporting both big-endian and little-endian data access via software-selectable mode. Its clock system integrates crystal/ceramic resonator support, sub-32.768 kHz oscillator for RTC, and programmable PLL for main system clock generation up to 20 MHz.

Peripheral integration includes three independent serial communication interfaces (SCI1–SCI3) with selectable baud rates and framing, eight 16-bit timer/counters with input capture/output compare capabilities, and an 8-channel 10-bit successive-approximation ADC with internal reference and conversion start trigger options.

Key Specifications

Pinout & Package

DF38099FP10V is housed in a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are defined across five I/O ports (P1–P5), dedicated reset, clock, and debug interface pins (NMI, FROMCKSTP, E8 signals), and peripheral-specific terminals for SCI, ADC, timers, and interrupts.

FAQ

What is the maximum operating frequency of the DF38099FP10V?

The DF38099FP10V supports a maximum system clock frequency of 20 MHz when using the on-chip PLL with an external crystal or resonator. This frequency is achievable across the full operating voltage range (2.7–5.5 V) and temperature range (−40°C to +85°C), as confirmed in the H8/38099 Group Hardware Manual Rev. 2.00. The DF38099FP10V's CPU core executes instructions at this clock rate with predictable timing for real-time control loops.

Does the DF38099FP10V include on-chip debug capability?

Yes, the DF38099FP10V supports hardware-based on-chip debugging via the E8 interface, using dedicated pins including NMI, P16, P36, and P37. As documented in the H8/38099 Group Hardware Manual, this interface enables breakpoints, watchpoints, register inspection, and real-time trace without requiring external JTAG adapters - though certain pins are reserved during E8 operation and cannot be used for general I/O simultaneously.

What ADC resolution and channel count does the DF38099FP10V provide?

The DF38099FP10V integrates an 8-channel, 10-bit successive-approximation ADC with internal voltage reference and sample-and-hold circuitry. All eight channels (AD0–AD7) are mapped to Port 3 pins (P30–P37), and conversions can be triggered by software, timer match, or external event. This ADC configuration is explicitly specified in Section 1.1 (Features) and Section 8 (Electrical Characteristics) of the DF38099FP10V hardware manual.

Is the DF38099FP10V qualified for automotive applications?

No, the DF38099FP10V is classified as a Standard-grade Renesas product, intended for industrial, office, and consumer equipment - not automotive or safety-critical systems. Per Renesas documentation, it is not designed, manufactured, or tested to AEC-Q100 standards or automotive temperature ranges. For automotive use, Renesas recommends devices explicitly marked "Automotive" or "High Quality" grade, such as selected RH850 or RL78 variants.

What package type and pin count does the DF38099FP10V use?

The DF38099FP10V uses a 100-pin LQFP package measuring 14 mm × 14 mm with 0.5 mm lead pitch and an exposed thermal pad. This package is confirmed in the "Pin Assignment" section (Section 1.3) of the H8/38099 Group Hardware Manual and is consistent across all members of the H8/38099F series, including DF38099FP10V. It supports standard reflow soldering profiles and provides sufficient I/O for complex embedded control applications.
