Renesas R5F140PKAFB#30

Overview

R5F140PKAFB#30 from Renesas is a 100-pin LFQFP, 512 KB code flash, 32 KB RAM, industrial-grade RL78/G13A microcontroller operating from 1.6–5.5 V with ultra-low 47 µA/MHz active current and guaranteed operation up to +105°C. It integrates 12-channel 10-bit ADC, 12-channel 16-bit timer, RTC, UART/LIN, I²C, CSI, and DMA for embedded control in motor drives and industrial HMI.

For engineers reviewing the R5F140PKAFB#30 datasheet, R5F140PKAFB#30 pinout, R5F140PKAFB#30 application, or R5F140PKAFB#30 equivalent, key selection considerations include its 100-pin LFQFP-0.5mm package, 512 KB flash/32 KB RAM configuration, industrial temperature rating (−40°C to +105°C), and support for LIN-bus communication and background data flash rewriting.

Technical Context

The R5F140PKAFB#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz on-chip oscillator) to 30.5 µs (32.768 kHz subsystem clock). Its memory map spans 1 MB address space with dual-bank register organization and on-chip debug capability.

Power management includes HALT, STOP, and SNOOZE modes; voltage detection (14-level LVD); and POR circuitry. Peripheral integration features 4-channel DMA, 16×16-bit multiplier/divider/MAC, and dual power domains (VDD/EVDD0/EVDD1) with separate analog ground (EVSS0/EVSS1) for noise-sensitive mixed-signal operation.

FAQ

What is the maximum operating frequency and corresponding supply voltage range for the R5F140PKAFB#30?

The R5F140PKAFB#30 supports up to 32 MHz using its high-speed on-chip oscillator with ±1.0% accuracy across VDD = 1.6–5.5 V and TA = −40°C to +85°C. At 20 MHz main system clock (X1 crystal), operation is guaranteed up to +105°C with VDD ≥ 2.7 V. The device also supports lower-frequency modes including 32.768 kHz subsystem clock for RTC and ultra-low-power sleep states.

Does the R5F140PKAFB#30 support LIN bus communication, and which UART channel implements it?

Yes, the R5F140PKAFB#30 supports LIN bus communication on UART2 (pins P13/TxD2 and P14/RxD2), which includes dedicated LINSEL pin functionality and automatic sync-break detection per LIN 2.2A specification. This enables direct connection to LIN transceivers without external protocol translation, reducing BOM cost and board space in automotive body electronics and industrial sub-nodes.

How many analog input channels does the R5F140PKAFB#30 provide, and what reference voltage options are available?

The R5F140PKAFB#30 provides 20 analog input channels (ANI0–ANI19 plus ANI20 on P100), with 10-bit resolution and selectable 8-bit mode. Reference voltage options include external AVREFP/AVREFM pins, internal 1.45 V bandgap reference (available only in HS mode), and VDD as reference. The internal temperature sensor shares the ADC channel and is calibrated at factory for ±2°C accuracy across −40°C to +105°C.

What packaging and ordering options are available for the R5F140PKAFB#30, and what does the "#30" suffix indicate?

The R5F140PKAFB#30 is supplied in LFQFP-100 (14 × 14 mm, 0.5-mm pitch) tray packaging. The "#30" suffix denotes tray packaging per JEDEC standard J-STD-020, with 90 units per tray. Other options include #10 (tray, lead-free) and #50 (embossed tape, 1,000 units per reel). All variants share identical electrical and thermal specifications - only packaging format differs.

Can the R5F140PKAFB#30 perform simultaneous program execution and data flash rewriting, and what is the endurance rating?

Yes, the R5F140PKAFB#30 supports background operation (BGO) for data flash rewriting: instructions execute from code flash while 8 KB data flash is rewritten. Endurance is rated at 1,000,000 write/erase cycles (typ.) at VDD = 1.8–5.5 V. Each 1 KB block can be independently erased, and the flash shield window function prevents unauthorized access during field updates - critical for secure firmware OTA deployments.
