Product details
Overview
R5F12048GNA#60 from Renesas Electronics is an RL78/G15 16-pin, 8 KB flash, 1 KB RAM, industrial-grade 16-bit microcontroller operating at 2.4–5.5 V. It integrates a 16-channel A/D converter (8/10-bit), dual comparators, 8-channel 16-bit timer array, UART, two simplified I²C interfaces, and high-speed on-chip oscillator (1–16 MHz ±1.0% @ −20 to +85°C). Used in motor control subsystems, sensor interface modules, and industrial HMI panels.
For engineers reviewing the R5F12048GNA#60 datasheet, R5F12048GNA#60 pinout, R5F12048GNA#60 application, or R5F12048GNA#60 equivalent, key selection criteria include its HWQFN-16 (3 × 3 mm, 0.5 mm pitch) package, −40 to +105°C industrial temperature rating, 1 KB data flash with 1M rewrite cycles, and support for background operation-free low-power STOP/HALT modes.
Technical Context
The R5F12048GNA#60 implements the RL78-S2 CPU core with CISC architecture, 3-stage pipeline, and 1 MB address space. Its memory subsystem includes 8 KB code flash (1 KB block erase), 1 KB data flash (512 B blocks, 32-bit rewrite unit), and 1 KB SRAM - all accessible under single-supply operation.
Peripherals are organized around a unified interrupt controller supporting 16 internal and 8 external vectored sources. Clock generation combines selectable high-speed on-chip oscillator (1–16 MHz), low-speed 15 kHz on-chip oscillator, and external crystal (X1/X2, 1–12 MHz) or EXCLK input, with programmable power-on-reset voltage thresholds (2.25/2.68/3.02/4.45 V).

FAQ
What is the maximum operating frequency and accuracy of the on-chip oscillator in R5F12048GNA#60?
The R5F12048GNA#60 features a high-speed on-chip oscillator selectable from 1–16 MHz, with ±1.0% frequency accuracy over −20 to +85°C ambient temperature. At full 16 MHz operation, minimum instruction execution time is 0.0625 μs. Accuracy degrades to ±1.5% at −40 to −20°C and +85 to +105°C, consistent with its G-grade industrial qualification.
Does R5F12048GNA#60 support in-system programming without external hardware?
Yes, R5F12048GNA#60 supports self-programming of code and data flash memory using on-chip resources. It includes an on-chip debug function accessible via TOOL0/TOOLRxD/TOOLTxD pins, enabling firmware updates and debugging without external emulators - though Renesas cautions against using debug features in mass-production units due to flash endurance limits.
How many analog input channels does R5F12048GNA#60 provide, and what is their resolution?
R5F12048GNA#60 provides 7 analog input channels (ANI0–ANI6) with selectable 8-bit or 10-bit resolution. The A/D converter operates across the full 2.4–5.5 V supply range and includes an internal 0.815 V reference voltage, enabling accurate measurements without external reference components in most industrial sensing applications.
What package type and pin count does R5F12048GNA#60 use, and what are its thermal requirements?
R5F12048GNA#60 uses a 16-pin HWQFN package (3 × 3 mm, 0.5 mm pitch) with an exposed die pad. The pad must be soldered to a non-electrical thermal pad on the PCB for reliable heat dissipation and mechanical stability. This compact package supports high-density layouts while maintaining −40 to +105°C industrial operating capability.
Can R5F12048GNA#60 operate from a single 3.3 V supply, and what are its low-power mode capabilities?
Yes, R5F12048GNA#60 operates from a single 2.4–5.5 V supply, making 3.3 V fully compatible. It supports HALT mode (core clock stopped, peripherals active) and STOP mode (all clocks halted, RAM retained), achieving ultra-low standby current. These modes are essential for battery-powered industrial sensors and energy-harvesting applications where microamp-level quiescent current is critical.
