Renesas R5F11ZBADFP#10

Overview

R5F11ZBADFP#10 from Renesas Electronics is a 16-bit RL78/G1P microcontroller in a 32-pin LQFP package, featuring 32 KB flash memory, 2.5 KB RAM, and integrated 10-bit ADC with 8 channels. It operates at up to 24 MHz, supports on-chip debug, and targets low-power embedded control applications such as sensor interfaces and appliance motor control.

For engineers reviewing the R5F11ZBADFP#10 datasheet, R5F11ZBADFP#10 pinout, R5F11ZBADFP#10 application, or R5F11ZBADFP#10 equivalent, key selection criteria include its 32-pin LQFP-32 footprint, 32 KB flash/2.5 KB RAM configuration, RL78 CPU core with 1.62–5.5 V operation, and support for I²C, UART, and timer-based PWM generation.

Technical Context

The R5F11ZBADFP#10 implements the RL78 CPU core with CISC architecture, 16-bit data bus, and 20-bit address space. It integrates a high-speed on-chip oscillator (1–24 MHz), sub-clock oscillator (32.768 kHz), and programmable system clock divider to support multiple power modes including HALT and STOP.

Peripheral integration includes an 8-channel 10-bit ADC with sample-and-hold, 3x 16-bit timers (with PWM output capability), 1x serial array unit (SAU) supporting UART/I²C/SPI, and a watchdog timer with independent clock source. All peripherals are controlled via dedicated SFRs mapped in the 2nd SFR area.

FAQ

What is the maximum operating frequency of the R5F11ZBADFP#10?

The R5F11ZBADFP#10 supports a maximum system clock frequency of 24 MHz when using the high-speed on-chip oscillator with appropriate division settings. This frequency is achievable across the full 1.62–5.5 V supply range and ambient temperature range of –40°C to +85°C, as confirmed in the RL78/G1P Electrical Characteristics table.

Does the R5F11ZBADFP#10 include an integrated voltage regulator?

Yes, the R5F11ZBADFP#10 includes an on-chip voltage regulator controlled via the REGC pin. An external 1.0 μF ceramic capacitor must be connected between REGC and VSS to ensure stable regulation for internal analog circuits and flash programming operations.

How many ADC channels does the R5F11ZBADFP#10 support, and what is their resolution?

The R5F11ZBADFP#10 supports eight 10-bit ADC input channels mapped to P20–P27. Each channel provides 10-bit resolution with ±1 LSB integral nonlinearity and uses an internal 1.45 V reference voltage, eliminating need for external reference components in most sensor interface designs.

Is the R5F11ZBADFP#10 pin-compatible with other RL78/G1P variants?

Yes, the R5F11ZBADFP#10 shares identical pinout and package (LQFP-32) with all other 32-pin RL78/G1P devices including R5F11ZBAGFP#10 and R5F11ZBAxFP (x = A/D). Pin functions and electrical characteristics are consistent across this variant group per the RL78/G1P User's Manual Rev.1.00.

What debug interface does the R5F11ZBADFP#10 support?

The R5F11ZBADFP#10 supports Renesas' on-chip debug interface using the single-wire SWD (Serial Wire Debug) protocol. No external debug probe is required-debugging and flash programming are performed through the RESET and P10 pins using standard Renesas E2/E2 Lite emulators or compatible third-party tools.
