It integrates RTC, 12-channel 10-bit ADC, dual UART/LIN, I²C, CSI, and programmable buzzer output for embedded control in motor drives and industrial HMI.

For engineers reviewing the R5F140PKGFB#30 datasheet, R5F140PKGFB#30 pinout, R5F140PKGFB#30 application, or R5F140PKGFB#30 equivalent, key selection criteria include its -40°C to +105°C industrial temperature rating, 100-pin LFQFP (0.5 mm pitch) package, 512 KB flash/32 KB RAM memory configuration, and support for background data flash rewriting (1M cycles) and real-time clock calendar functionality.

Technical Context

The R5F140PKGFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction execution time (0.03125 µs @ 32 MHz high-speed on-chip oscillator or 30.5 µs @ 32.768 kHz subsystem clock). It supports dual power domains (VDD/EVDD0/EVDD1) and separate ground paths (VSS/EVSS0/EVSS1) for noise-sensitive analog and digital operation.

Its peripheral set includes four serial array units (UART0–3, I²C0–3, CSI0–3), 12-channel 16-bit timer array, 12-bit interval timer, watchdog timer, and hardware multiplier/divider/multiply-accumulator - all accessible via 100 I/O pins including 20 analog inputs (ANI0–ANI20), key return (KR0–KR7), and programmable clock/buzzer outputs (PCLBUZ0/PCLBUZ1).

FAQ

What is the maximum operating frequency and corresponding current consumption of the R5F140PKGFB#30?

The R5F140PKGFB#30 operates at up to 32 MHz using its high-speed on-chip oscillator, with typical active current of 47 µA/MHz. At full 32 MHz operation, this equates to approximately 1.5 mA total active current - verified under VDD = 3.3 V and TA = 25°C conditions per R01DS0376EJ0110 Rev.1.10.

Does the R5F140PKGFB#30 support background data flash rewriting while executing application code?

Yes, the R5F140PKGFB#30 supports Background Operation (BGO) for data flash, allowing instructions to be fetched and executed from program memory during data flash erase/write cycles. This enables seamless runtime parameter updates without halting application logic - confirmed in Section 1.1 Features and Section 1.6 Outline of Functions of the datasheet.

How many analog input channels does the R5F140PKGFB#30 provide, and what is their resolution?

The R5F140PKGFB#30 provides 20 analog input channels (ANI0–ANI20) with 10-bit resolution. It includes internal 1.45 V reference voltage and an integrated temperature sensor - both usable only in HS (high-speed main) mode per Note 1 in the datasheet's 1.1 Features section.

What is the purpose of the EVDD0, EVDD1, EVSS0, and EVSS1 pins on the R5F140PKGFB#30?

EVDD0 and EVDD1 are dedicated power supplies for analog I/O ports and analog peripherals respectively; EVSS0 and EVSS1 are their corresponding ground returns. These pins enable physical separation of analog and digital power/ground paths - a design requirement for achieving high ADC accuracy and minimizing noise coupling, as specified in the 100-pin pin configuration cautions.

Can the R5F140PKGFB#30 operate across the full industrial temperature range of -40°C to +105°C?

Yes, the R5F140PKGFB#30 is rated for operation from -40°C to +105°C ambient temperature, as indicated by the "G" suffix in its part number per Figure 1-1 and Table 1-1 of the datasheet. This guarantee applies specifically to devices with 384 KB or 512 KB code flash memory - which includes the R5F140PKGFB#30.
