Product details
Overview
R5F12048MNA#00 from Renesas Electronics is an RL78/G15 16-pin HWQFN microcontroller with 8 KB code flash, 1 KB data flash, and 1 KB RAM, operating at 2.4–5.5 V across −40°C to +125°C. It integrates an RL78 CPU core (3-stage pipeline), 8-channel 16-bit timer array, 7-channel 8/10-bit A/D converter, 1-channel comparator, UART, 2-channel simplified I²C, and 1-channel simplified SPI (CSI), targeting industrial motor control and sensor interface applications.
For engineers reviewing the R5F12048MNA#00 datasheet, R5F12048MNA#00 pinout, R5F12048MNA#00 application, or R5F12048MNA#00 equivalent, this page delivers verified package mapping (HWQFN-16, 3 × 3 mm, 0.5-mm pitch), confirmed industrial-grade temperature support (+125°C), validated peripheral count (7 ADC channels, 2 CSI channels), and real-world timing accuracy (±1.0% @ −20°C to +85°C for high-speed on-chip oscillator).
Technical Context
The R5F12048MNA#00 implements the RL78-S2 CPU core with CISC architecture, supporting instruction execution times from 0.0625 μs (16 MHz) to 1.0 μs (1 MHz), and features a 1 MB address space with four banks of 8-bit general-purpose registers. Its clock system combines a selectable high-speed on-chip oscillator (1–16 MHz, ±1.0% accuracy over −20°C to +85°C) and a dedicated 15 kHz low-speed on-chip oscillator for watchdog operation.
Power management includes HALT and STOP modes, selectable power-on-reset (SPOR) with four voltage thresholds (2.25–4.45 V), and true low-power design enabling 54 µA/MHz operation at TA = 125°C. Peripheral integration includes TAU0 timer array (8 channels), SAU0 serial array unit (2 channels), and on-chip BCD correction logic - all mapped to 14 I/O pins in the HWQFN-16 package.

FAQ
What is the package type and pin count of the R5F12048MNA#00?
The R5F12048MNA#00 uses a 16-pin HWQFN package measuring 3 mm × 3 mm with 0.5 mm pitch and an exposed thermal pad. This compact, thermally efficient package is explicitly designated by the "NA" suffix in the part number and confirmed in Table 1-1 of the R01DS0420EJ0140 datasheet for 16-pin HWQFN variants.
Does the R5F12048MNA#00 support in-system programming without external hardware?
Yes, the R5F12048MNA#00 supports self-programming of both code and data flash memory using its on-chip debug function - no external programmer is required. The device includes flash shield window functionality and operates with VDD = 2.4–5.5 V during rewrites, as specified in the "Self-programming" and "Data flash memory" sections of the datasheet.
What is the maximum number of analog input channels supported by the R5F12048MNA#00?
The R5F12048MNA#00 supports up to 7 analog input channels (ANI0–ANI6), as confirmed in the "Outline of Functions" table (Page 17) and the 16-pin HWQFN pin configuration (Page 8). This matches the 16-pin variant's specification and exceeds the 3–4 channels available in smaller 8- and 10-pin RL78/G15 devices.
How does the oscillator accuracy of the R5F12048MNA#00 compare to consumer-grade variants?
The R5F12048MNA#00 offers ±1.0% high-speed on-chip oscillator accuracy over −20°C to +85°C, tighter than the ±2.0% spec for A-grade (consumer) parts. At extended temperatures (−40°C to −20°C and +85°C to +125°C), it maintains ±1.5% accuracy - a key differentiator for industrial applications requiring stable timing without external crystals.
Can the R5F12048MNA#00 operate reliably at 125°C ambient temperature?
Yes, the R5F12048MNA#00 is rated for continuous operation from −40°C to +125°C (M-grade industrial), with electrical specifications validated across this range. Its 54 µA/MHz active current at TA = 125°C and guaranteed flash rewrite endurance (1,000,000 cycles) confirm suitability for high-temperature industrial deployments such as motor drives and power supplies.
