Product details
Overview
R5F12048ANA#00 from Renesas Electronics is an RL78/G15 16-pin, 8 KB flash, 1 KB RAM, 2.4–5.5 V ultra-low-power 16-bit MCU with integrated 8/10-bit ADC (7 channels), dual simplified I²C, UART, and 8-channel 16-bit timer array - deployed in industrial sensor nodes and battery-powered control modules requiring TA = −40°C to +125°C operation.
For engineers reviewing the R5F12048ANA#00 datasheet, R5F12048ANA#00 pinout, R5F12048ANA#00 application, or R5F12048ANA#00 equivalent, key selection criteria include HWQFN-16 (3 × 3 mm, 0.5 mm pitch) thermal performance, high-speed on-chip oscillator accuracy (±1.0% at −20 to +85°C), data flash endurance (1M rewrites), and interrupt support across 8 external sources and 16 internal vectors.
Technical Context
The R5F12048ANA#00 implements the RL78-S2 CPU core with a 3-stage CISC pipeline, 1 MB address space, and configurable instruction timing (0.0625 μs min @ 16 MHz). It integrates a selectable power-on-reset circuit with four voltage thresholds (2.25–4.45 V) and supports both crystal (X1/X2, 1–12 MHz) and high-speed on-chip oscillator (1–16 MHz) clock sources.
Its peripheral set includes two serial array units (SAU0) enabling simultaneous CSI00/CSI01 and IIC00/IIC01 operation, one UART0 channel, up to 7 PWM outputs via TAU0 timer array, and dual comparators (1 active in 16-pin variants). The device uses background operation–independent data flash (no BGO) and executes instructions only from code flash during rewrite.

The R5F12048ANA#00 high-speed on-chip oscillator supports frequencies up to 16 MHz, with factory-trimmed accuracy of ±1.0% over −20°C to +85°C. This allows the R5F12048ANA#00 to achieve a minimum instruction execution time of 0.0625 μs without external clock components, reducing bill-of-materials cost and board space.
Does the R5F12048ANA#00 support background operation during data flash rewriting?
No, the R5F12048ANA#00 does not support background operation (BGO) for data flash rewriting. During data flash write/erase operations, instruction execution from code flash memory is halted. This behavior is explicitly documented in the R5F12048ANA#00 datasheet and requires firmware to manage critical sections accordingly.

The R5F12048ANA#00 provides 7 analog input channels (ANI0 through ANI6) accessible via P00–P07 pins. These channels support both 8-bit and 10-bit resolution A/D conversion with an internal reference voltage of 0.815 V (TYP.), enabling accurate ratiometric measurements in sensor interface applications.
What package type and dimensions does the R5F12048ANA#00 use?
The R5F12048ANA#00 uses a HWQFN-16 package measuring 3 mm × 3 mm with 0.5 mm pitch and an exposed thermal pad. This compact, thermally efficient package is specified in the R5F12048ANA#00 ordering information and supports high-density PCB layouts in space-constrained industrial modules.
Can the R5F12048ANA#00 operate across the full industrial temperature range?
Yes, the R5F12048ANA#00 is qualified for operation from −40°C to +125°C (M-grade), meeting stringent industrial requirements. Its electrical specifications - including oscillator accuracy, ADC performance, and I/O drive strength - are guaranteed across this full range, as confirmed in the R5F12048ANA#00 datasheet revision 1.40.
