R5F2138ASNFP#V0 Equivalent & Substitute Parts

Part Overview

The R5F2138ASNFP#V0 is a 16-bit microcontroller IC from Renesas Electronics, based on the R8C core processor architecture. This device integrates 96KB of FLASH program memory, 8KB of RAM, and 4KB of EEPROM, operating at 20MHz with a supply voltage range of 1.8V to 5.5V. The microcontroller features integrated connectivity options including I2C, LINbus, SIO, SSU, and UART/USART interfaces, along with peripheral functions such as power-on reset (POR), pulse-width modulation (PWM), voltage detection, and watchdog timer (WDT). The device is housed in an 80-pin LQFP surface-mount package measuring 12x12mm with 75 I/O pins.

The R5F2138ASNFP#V0 carries an obsolete product status, making identification of functionally equivalent alternatives necessary for ongoing design support, maintenance, and component procurement. Substitute parts must maintain electrical and mechanical compatibility across core processor architecture, memory configuration, operating parameters, and package specifications.

Substitute Part Grouping Explanation

Substitution of the R5F2138ASNFP#V0 is determined by strict equivalence across the following electrical and mechanical parameters:

Core Architecture & Processing: The substitute part must utilize the R8C core processor with identical 16-bit core size and 20MHz operating frequency to ensure instruction set compatibility and timing characteristics.

Memory Configuration: Program memory must be FLASH type with 96KB capacity (96K x 8 organization). EEPROM must be 4K x 8 and RAM must be 8K x 8 to maintain software compatibility and data storage capacity.

Electrical Specifications: Supply voltage range must span 1.8V to 5.5V. Data converter specification must match at A/D 20x10b. Connectivity interfaces (I2C, LINbus, SIO, SSU, UART/USART) and peripheral functions (POR, PWM, Voltage Detect, WDT) must be present.

Physical Package: The 80-pin LQFP surface-mount package with 12x12mm dimensions and 75 I/O pins is mandatory for PCB layout compatibility.

Operating Environment: Temperature range of -20°C to 85°C must be maintained.

The R5F2138ASNFP#30 qualifies as a direct substitute based on complete alignment with all specified parameters.
