R5F104GDAFB#V0

Microcontrollers Overview

The R5F104GDAFB#V0 is a 16-bit microcontroller from the Renesas RL78/G14 family, featuring an RL78 CPU core with CISC architecture. It includes 48 kB of code flash memory and 5.5 kB of on-chip RAM. The device operates within a voltage range of 1.6 V to 5.5 V and supports a maximum clock frequency of 32 MHz. It is housed in a 48-pin LFQFP package and is rated for industrial operating temperatures between -40°C and +105°C.

Microcontrollers Feature Summary

• Ultra-low power consumption technology supporting multiple low-power modes including HALT, STOP, and SNOOZE.
• Integrated high-speed on-chip oscillator with selectable frequencies up to 64 MHz and high accuracy.
• Supports background operation allowing program execution while rewriting data flash memory.
• Includes event link controller for linking peripheral functions to interrupt sources.

Microcontrollers Applications

• Industrial control systems requiring wide temperature operation
• General-purpose embedded applications
• Low-power consumer electronics

Microcontrollers Procurement Notes

Verify the specific ordering suffix #V0 corresponds to the required tray packaging specification for LFQFP packages. Confirm that the industrial temperature grade (D) matches the application requirements of -40°C to +85°C or verify if the G variant is needed for +105°C support. Ensure compatibility with existing design files regarding pin assignments and memory maps.

Microcontrollers Selection Notes

Select this component when a balance of moderate flash capacity and low power consumption is required for industrial environments. The 48-pin LFQFP package offers a compact footprint suitable for space-constrained designs. Consider the available I/O count and peripheral channels against system interface needs before finalizing the selection.

Microcontrollers Part Context

This part belongs to the RL78/G14 series, designed for general-purpose applications. It shares architectural similarities with other members of the family but differs in memory size and package options. The D suffix indicates the industrial temperature range, distinguishing it from consumer-grade variants.

Microcontrollers Replacement Considerations

Check for direct substitutes within the RL78/G14 family with matching memory sizes and packages. Verify pin-to-pin compatibility if replacing with higher or lower memory variants. Consult official documentation for any changes in peripheral configurations or electrical characteristics.
