R7FA0E3034ZSD#VA0 is the tube-packed orderable form of the Renesas Electronics RA0E3 entry-level microcontroller, built on a 32 MHz Arm Cortex-M23 core with 16 KB code flash and 2 KB SRAM in a 20-pin TSSOP package. It is designed for the small auxiliary job that does not justify a large MCU: a serial array unit covering simplified SPI, simplified I2C and UART with LIN-bus support, plus an I2C bus interface, a 10-bit ADC with 6 channels and an integrated temperature sensor, 8 timer array channels with 7 PWM outputs, a 32-bit interval timer, a data transfer controller and safety functions including CRC and an independent watchdog. The business gain is BOM cost reduction: a wide 1.6 V to 5.5 V operating range with 5 V system compatibility, a high-accuracy on-chip oscillator and -40 °C to +125 °C operation let the part drop into existing designs as a sub-controller for sensing, safety locks or basic system control without extra level shifters or external oscillators. Evidence: the Renesas RA0E3 Group Datasheet (R01DS0500EJ0100 Rev. 1.00) lists this part with its product configuration and part-numbering scheme, and Renesas positions the RA0E3 as pin-compatible with the RA0E1 and RA0E2 for design scalability across the RA0 series. Selection and procurement advice: choose the RA0E3 where 16 KB flash and the trimmed peripheral set cover the sub-function; stay with the RA0E1 or RA0E2 where more memory or peripherals are needed; the trailing #VA0 denotes tube (magazine) packing (the #HA0 variant denotes tape and reel), so state the packing form in your RFQ and match the full R7FA0E3034ZSD#VA0 code.

State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.
R7FA0E3034ZSD#VA0 is a 32-bit microcontroller from Renesas Electronics, orderable in the TSSOP-20 package. The ordering code fixes the exact configuration you receive — package, grade and packing — so procurement starts with matching this code character-for-character against your BOM, not just the base series name.
When you request a quote, include the full ordering code, the target packing format (reel, tube, tray or cut tape), your quantity and any date-code or lot requirements. We reconfirm manufacturer, suffix, package, date code and traceability against the actual offered lot before any commercial quote is issued, and every RFQ gets a reply within 24 hours.

Browse existing catalog records — same series first, then the same category and manufacturer. These are not confirmed replacements; compatibility requires engineering review.
Every suffix in a manufacturer ordering code identifies one exact orderable device — package, temperature grade, packing format or a revision. R7FA0E3034ZSD#VA0 names the TSSOP-20 configuration; a code that differs by even one suffix character may be a different device. Always quote the complete code exactly as it appears on your BOM.
The package (TSSOP-20) is the physical form of the device itself. Packing describes how the devices are delivered — reel, tube, tray or cut tape. The same ordering code can ship in different packing formats depending on the lot, so confirm the required packing format when you submit your RFQ.
Traceability evidence — lot and date-code information, labels and photos — is confirmed per lot at quotation time, because it depends on the actual lot offered. Tell us which documents your receiving inspection requires when you submit the RFQ, and we will confirm what can be provided for the offered lot.
Add R7FA0E3034ZSD#VA0 to your RFQ with the complete ordering code, the manufacturer (Renesas Electronics), your quantity, the target packing format and any date-code requirements. We reply to every RFQ within 24 hours.
