Renesas R5F12048ANA#60

Overview

R5F12048ANA#60 from Renesas Electronics is an 8 KB flash, 1 KB RAM RL78/G15 16-pin microcontroller with 7-channel 8/10-bit ADC, dual simplified I²C, UART, and 8-channel 16-bit timer array - designed for low-power industrial sensor nodes and motor control interfaces operating from 2.4–5.5 V across −40°C to +125°C.

For engineers reviewing the R5F12048ANA#60 datasheet, R5F12048ANA#60 pinout, R5F12048ANA#60 application, or R5F12048ANA#60 equivalent, this page delivers verified package mapping (HWQFN-16), validated peripheral configurations (including PCLBUZ0 clock/buzzer output and VCOUT0 comparator output), and real-world timing and analog performance metrics aligned to M-grade industrial operation.

Technical Context

The R5F12048ANA#60 implements the RL78 CPU core with 3-stage CISC pipeline, supporting minimum instruction execution at 0.0625 μs (16 MHz high-speed on-chip oscillator) or 1.0 μs (1 MHz). It integrates a selectable power-on-reset circuit with four voltage thresholds (2.25–4.45 V) and operates with true low-power HALT/STOP modes.

Its analog subsystem includes a 7-channel 8/10-bit ADC with internal 0.815 V reference, two comparators (IVCMP0/IVREF0), and programmable clock/buzzer output (PCLBUZ0). Serial connectivity comprises one UART channel, two simplified SPI (CSI) channels, and two simplified I²C channels - all multiplexed on dedicated port pins with peripheral I/O redirection support.

FAQ

What is the maximum operating frequency of the R5F12048ANA#60 high-speed on-chip oscillator?

The R5F12048ANA#60 supports a high-speed on-chip oscillator frequency of up to 16 MHz, with ±1.0% accuracy over −20°C to +85°C and ±1.5% over −40°C to −20°C or +85°C to +125°C. This enables a minimum instruction execution time of 0.0625 μs and supports real-time control loops in motor and power applications.

Does the R5F12048ANA#60 support background data flash rewriting while executing code from main flash?

No, the R5F12048ANA#60 does not support background operation (BGO) for data flash. During data flash memory rewriting, instruction execution from code flash memory is halted. The device requires careful state management - typically entering STOP mode or halting CPU execution - before initiating data flash writes.

How many analog input channels are available on the R5F12048ANA#60, and what is their resolution?

The R5F12048ANA#60 provides 7 analog input channels (ANI0–ANI6) with configurable 8-bit or 10-bit resolution. Conversion uses VDD as reference by default, and an internal 0.815 V reference is available for ratiometric measurements independent of supply variation.

What is the purpose of the PCLBUZ0 pin on the R5F12048ANA#60, and how is it configured?

The PCLBUZ0 pin on the R5F12048ANA#60 serves as a programmable clock or buzzer output, capable of generating frequencies up to 10 MHz. It is configured via the clock output control register (COCR) and can drive piezoelectric buzzers directly or provide clock signals to external ICs without external oscillators.

Is the R5F12048ANA#60 pin-compatible with other RL78/G15 variants in the HWQFN-16 package?

Yes, the R5F12048ANA#60 shares identical pinout and electrical characteristics with all other RL78/G15 devices in the HWQFN-16 package (e.g., R5F12047ANA#60, R5F12048GNA#60, R5F12048MNA#60), enabling drop-in replacement within the same temperature grade and flash size family.
