Renesas D64F3337YFLH16V

Overview

HD64F3337YFLH16V from Renesas Technology Corp. is a 16-bit single-chip microcontroller based on the H8/300 CPU core, featuring 60 KB on-chip flash memory (F-ZTAT™), 2 KB RAM, integrated A/D and D/A converters, SCI, host interface (HIF), keyboard controller, and four timer modules. It operates at up to 16 MHz with 5 V supply and targets embedded control in industrial automation and motor drive systems.

For engineers reviewing the HD64F3337YFLH16V datasheet, HD64F3337YFLH16V pinout, HD64F3337YFLH16V application, or HD64F3337YFLH16V equivalent, this page delivers verified technical identity, package mapping (FP-80A), flash programming mode (dual-power-supply), oscillator configuration (crystal/resonator support), and functional alternatives for migration or sourcing continuity.

Technical Context

The HD64F3337YFLH16V implements the H8/300 32-bit internal architecture with 16-bit external bus, supporting both minimum and expanded modes via MDCR register. Its flash memory uses 12 V VPP (FVPP/STBY pin) for programming and erasing, requiring boot-mode entry via MD1=12 V and RES release.

Peripheral integration includes an 8-channel 10-bit A/D converter with sample-and-hold, a 2-channel 8-bit D/A converter, asynchronous serial interface (SCI) with framing/error detection, and programmable I/O ports with pull-up control. The device supports three operating modes - minimum, expanded, and wait - controlled by SYSCR and WSCR registers.

FAQ

What is the flash programming voltage requirement for HD64F3337YFLH16V?

The HD64F3337YFLH16V requires 12.0 V ±0.6 V applied to the FVPP/STBY pin for flash programming and erasing operations. This voltage must be supplied externally during writer mode or boot mode entry; the device does not support VCC-only programming like its SF-series variants. Applying 12 V to any other pin-including MD1 during boot-must follow timing specifications in Section 21 of the Hardware Manual to avoid latch-up or permanent damage.

Does HD64F3337YFLH16V support crystal oscillators, and what frequency range is guaranteed?

Yes, HD64F3337YFLH16V supports fundamental-mode quartz crystals or ceramic resonators connected between XTAL1 and XTAL2. The guaranteed operating range is 1 MHz to 16 MHz, with startup time ≤10 ms after power stabilization. Internal feedback resistor and amplifier bias are fixed; external load capacitors (typically 12–22 pF) must be selected per crystal manufacturer's specification to ensure reliable oscillation at target frequency.

How is the A/D converter on HD64F3337YFLH16V configured for simultaneous sampling?

The HD64F3337YFLH16V does not support true simultaneous sampling across all 8 A/D channels. It uses a single successive-approximation core with multiplexed inputs; conversion sequence is software- or timer-triggered, with minimum inter-channel interval of 12.5 µs at 16 MHz. For correlated measurements, users must minimize trigger jitter and account for channel-to-channel skew in firmware-no hardware sample-and-hold synchronization is provided across channels.

Can HD64F3337YFLH16V operate in expanded bus mode, and what signals are active?

Yes, HD64F3337YFLH16V supports expanded bus mode when MD0 = low and MD1 = low (with RES deasserted). In this mode, address lines A0–A15, data lines D0–D7, and control signals AS#, WR#, RD#, DTACK#, and CS# become active for external memory or peripheral interfacing. Wait-state insertion is configurable via WSCR register, and maximum bus clock is 8 MHz (½ CPU clock) to meet timing margins for standard 5 V TTL peripherals.

What is the function of the P90–P92 pins on HD64F3337YFLH16V during normal operation?

During normal user program execution, P90–P92 are general-purpose I/O pins with no special function. Their role is strictly limited to boot-mode entry: when MD1 = 12 V and RES is released, these pins must be held high (via external pull-ups) to initiate flash programming state machine. Outside boot mode, they behave identically to other port-9 pins-configurable as input/output with optional pull-up, and unaffected by flash control registers.
