Microcontrollers Procurement Notes

Verify the specific ordering suffix #X0 corresponds to the embossed tape packaging specification for LFQFP/LQFP packages as defined in the Renesas RL78/G14 datasheet. Confirm that the 'A' field indicates consumer application rating (-40 to +85°C) matches your environmental requirements. Cross-reference the exact part number against the latest official Renesas Electronics ordering list to ensure current availability and correct pinout configuration.

Microcontrollers Selection Notes

Select this component when a balance of moderate program memory size and extensive I/O count is required. The 64-pin package provides access to numerous peripheral channels suitable for complex interface requirements. Ensure the system design accommodates the 1.6 V minimum supply voltage if operating in low-voltage environments. Consider the thermal characteristics of the LQFP package for heat dissipation needs.

Microcontrollers Part Context

This microcontroller belongs to the RL78/G14 series, designed for general-purpose applications. It shares architectural similarities with other members like the R5F104FJGFP but differs in package type and potentially temperature grade. The 'J' designation indicates 256 KB flash memory, while 'F' denotes Flash memory type. The 'A' suffix specifies the consumer temperature range.

Microcontrollers Replacement Considerations

Direct replacements must match the 256 KB flash capacity and 64-pin LQFP footprint. Verify compatibility with alternative packages such as LFQFP if pinout flexibility exists. Check for identical peripheral configurations including ADC channels and timer counts to ensure functional parity without hardware redesign.
