Product details
Overview
DF36094GFZV from Renesas Electronics is a 16-bit single-chip microcomputer in the H8/300H Tiny 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 UART, I2C, timer modules, and 10-bit ADC - deployed in industrial control panels requiring deterministic real-time response.
For engineers reviewing the DF36094GFZV datasheet, DF36094GFZV pinout, DF36094GFZV application, or DF36094GFZV equivalent, key selection considerations include its 5V-tolerant I/O capability, subclock oscillator support for RTC operation, low-power sleep/standby modes, and compatibility with Renesas E7/E8 debug interfaces.
Technical Context
The DF36094GFZV implements the H8/300H CPU architecture with 24-bit address space, supporting up to 16 MB external memory expansion via multiplexed address/data bus. It integrates dual clock domains: main system clock (up to 20 MHz) derived from on-chip RC oscillator or external crystal, and independent 32.768 kHz subclock for real-time counter and wakeup timing.
Peripheral subsystems include three 16-bit timer/counters (one with input capture/output compare), two serial interface modules (SCI0/SCI1 supporting UART and clock-synchronous modes), and a 10-channel 10-bit successive-approximation ADC with internal reference voltage - all accessible via dedicated register sets mapped into the CPU's I/O space.

FAQ
What is the maximum operating frequency supported by DF36094GFZV?
The DF36094GFZV supports a maximum system clock frequency of 20 MHz when driven by an external crystal or the calibrated on-chip RC oscillator. This enables a 500 ns minimum instruction cycle time, ensuring deterministic timing for real-time control loops. The CKCSR register controls clock source selection and prescaler configuration to maintain stability across voltage and temperature ranges.
Does DF36094GFZV include on-chip debug support?
Yes, DF36094GFZV is fully compatible with Renesas E7 and E8 on-chip emulators. Debug access uses dedicated pins (NMI, P85, P86, P87), though these pins are reserved during emulation and cannot be used for user I/O simultaneously. Address ranges H'7000–H'7FFF and H'F780–H'FB7F are also allocated to the emulator and must be excluded from application code.
What power-saving modes does DF36094GFZV offer?
DF36094GFZV provides four low-power modes: Sleep (CPU halted, peripherals active), Standby (CPU and most peripherals halted, RAM retained), Subsleep (subclock active, RTC running, <1.2 μA), and Subactive (subclock domain active, selected modules operational). Mode transitions are controlled via SYSCR1/SYSCR2 registers and triggered by interrupts or reset events.
Can DF36094GFZV operate with a 32.768 kHz crystal for real-time clock functions?
Yes, DF36094GFZV includes dedicated X1/X2 pins for connecting a 32.768 kHz crystal to drive the subclock oscillator. This enables accurate real-time clock (RTC) operation and ultra-low-power wake-up from Subsleep mode. When unused, X1 must be grounded and X2 left open per Renesas Hardware Manual Section 5.6.2.
Is DF36094GFZV pin-compatible with other H8/3609x series devices?
Yes, DF36094GFZV shares the same 100-pin LQFP package and pin assignment with HD64F36094, HD64F36092, and HD64F36092G. This enables drop-in replacement within the H8/3609x family for memory-scaling upgrades or downgrades, provided firmware accounts for differences in ROM/RAM size and peripheral enable states.
