R5F11MPEAFB#10 Equivalent & Substitute Parts

Part Overview

The R5F11MPEAFB#10 is a 16-bit embedded microcontroller from Renesas Electronics Corporation belonging to the RL78/L1A series. This device integrates a RL78 core processor operating at 24MHz with 64KB FLASH program memory, 8KB EEPROM, and 5.5KB RAM in a 100-LFQFP surface mount package. The microcontroller provides comprehensive connectivity options including CSI, I2C, LINbus, SPI, and UART/USART interfaces, along with integrated peripherals such as LCD driver, low voltage detection (LVD), power-on reset (POR), PWM, and watchdog timer (WDT). With 79 I/O pins and dual 12-bit data converters (14-channel A/D and 2-channel D/A), this device serves applications requiring mid-range processing capability and extensive peripheral integration. The part maintains Active product status and carries ROHS3 compliance certification. Substitute parts are identified based on identical electrical specifications, memory configuration, and package compatibility to ensure direct functional replacement without design modification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the R5F11MPEAFB#10 are identified through strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

Core Architecture & Processing: The RL78 core processor, 16-bit architecture, and 24MHz operating frequency define the fundamental processing capability and instruction set compatibility.

Memory Configuration: Program memory capacity (64KB FLASH), EEPROM size (8K x 8), and RAM allocation (5.5K x 8) must be identical to ensure software compatibility and functional equivalence.

Electrical Characteristics: Supply voltage range (1.8V ~ 3.6V), data converter specifications (14-channel 12-bit A/D and 2-channel 12-bit D/A), and operating temperature range (-40°C ~ 85°C) must match exactly.

Connectivity & Peripherals: Identical support for CSI, I2C, LINbus, SPI, and UART/USART interfaces, plus LCD driver, LVD, POR, PWM, and WDT functionality.

Package & Physical Form: 100-LFQFP (14x14) surface mount package with 79 I/O pins ensures mechanical and electrical pin compatibility.

Compliance & Certification: ROHS3 compliance, MSL 3 rating, and REACH unaffected status must be maintained.

The R5F11MPEAFB#30 substitute part satisfies all these criteria, differing only in packaging designation (tray specification variant) while maintaining complete functional and electrical equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the R5F11MPEAFB#10 and R5F11MPEAFB#30 are Active product status devices from Renesas Electronics Corporation, ensuring ongoing manufacturer support and availability. Both parts carry identical ROHS3 compliance certification and REACH unaffected status, meeting environmental and regulatory requirements for industrial and commercial applications.

The parts are functionally equivalent across all electrical specifications, memory architecture, peripheral integration, and package configuration. Selection between these parts is determined by packaging and supply chain requirements rather than technical performance differences. The #10 and #30 designations reflect different tray packaging specifications from the manufacturer.

For applications requiring the RL78/L1A microcontroller with 64KB FLASH memory, 24MHz operation, and comprehensive peripheral support in a 100-LFQFP package, either part number provides identical functional performance. Component selection should be based on inventory availability, lead time, and packaging compatibility with assembly processes.

Both devices maintain MSL 3 moisture sensitivity rating with 168-hour floor life, requiring standard moisture control procedures during storage and handling. Operating temperature range of -40°C to 85°C supports industrial temperature applications without thermal derating.
