Product details
Overview
DF36037GFZJEV from Renesas Electronics is a 16-bit single-chip microcontroller in the H8/36037 Group, featuring the H8/300H CPU core, 128 KB on-chip ROM, 8 KB RAM, and integrated peripherals including SCI, I2C, and 10-bit ADC. It operates at up to 20 MHz and targets embedded control applications requiring deterministic real-time response and low-power operation.
For engineers reviewing the DF36037GFZJEV datasheet, DF36037GFZJEV pinout, DF36037GFZJEV application, or DF36037GFZJEV equivalent, key selection criteria include its 100-pin LQFP package, 3.3 V supply compatibility, built-in flash memory with in-system programming support, and power-down modes (Sleep, Standby, Subsleep) for energy-constrained systems.
Technical Context
The DF36037GFZJEV implements the H8/300H CPU architecture with full instruction set compatibility to the H8/300, supporting 16-bit data paths and 24-bit addressing. It integrates system-control modules (clock pulse generator, reset controller, power-down controllers) and on-chip peripherals including three serial communication interfaces (SCI), one I2C bus interface, and a 10-channel 10-bit successive-approximation ADC.
Its clock system supports crystal resonator (1–20 MHz), ceramic resonator, or external clock input, with programmable prescaler S enabling flexible peripheral clock derivation. The device includes dedicated registers for interrupt edge selection (IEGR1/IEGR2), enable control (IENR1/IENR2), and flag management (IRR1/IRR2/IWPR), supporting prioritized vectored interrupt handling with sub-µs response time.

FAQ
What is the maximum operating frequency of the DF36037GFZJEV?
The DF36037GFZJEV supports a maximum system clock frequency of 20 MHz, achievable using an external crystal resonator up to 20 MHz or an external clock source. This frequency enables instruction execution at 50 ns per cycle and supports real-time control loops with sub-millisecond latency. The device's clock pulse generator includes a programmable prescaler to derive lower-frequency clocks for peripherals without sacrificing CPU performance. DF36037GFZJEV maintains full functionality across its specified 3.0 V to 3.6 V supply range at this speed.
Does the DF36037GFZJEV include on-chip flash memory, and what is its capacity?
Yes, the DF36037GFZJEV integrates 128 KB of on-chip flash memory configured as program memory. This flash supports in-system programming (ISP) via on-chip boot ROM, allowing firmware updates without removing the device from the board. It provides ≥10,000 write/erase cycles and guaranteed data retention for over 20 years at 85°C. DF36037GFZJEV uses dedicated FLMCR1/FLMCR2 and FENR registers to manage read, write, and erase operations safely and reliably.
How many analog-to-digital converter (ADC) channels does the DF36037GFZJEV support?
The DF36037GFZJEV features a 10-bit successive-approximation ADC with 10 input channels (AD0–AD9), accessible via Port 8 pins (P80–P87) and additional dedicated pins. It supports software- and timer-triggered conversions, selectable sample-and-hold times, and built-in reference voltage options. The ADC delivers ±1 LSB integral nonlinearity across its full range, making it suitable for precision sensor interfacing in industrial and medical applications. DF36037GFZJEV's ADC module is fully documented in Section 7 of the H8/36037 Group Hardware Manual.
What low-power modes are available on the DF36037GFZJEV?
The DF36037GFZJEV implements four hardware-supported low-power modes: Sleep, Standby, Subsleep, and Subactive. These are controlled via SYSCR1 and SYSCR2 registers and reduce current consumption from ~15 mA (active) to as low as 1.5 µA (Subsleep). Each mode selectively gates clocks to CPU, peripherals, and RAM while preserving register contents and interrupt wake-up capability. DF36037GFZJEV's power-down architecture enables battery-powered operation in building controls and portable diagnostics without compromising responsiveness.
Is the DF36037GFZJEV pin-compatible with other members of the H8/36037 Group?
Yes, the DF36037GFZJEV shares identical pinout and electrical characteristics with other members of the H8/36037 Group, including HD64F36037G and HD64336037G, all packaged in 100-pin LQFP. Functionally identical variants differ only in marking, RoHS compliance status, or minor process revisions - enabling direct substitution in existing designs. DF36037GFZJEV maintains full compatibility with H8/36037 Group development tools, debuggers (E7/E8), and software libraries without hardware modification.
