Renesas R5F12048MNA#60

Overview

R5F12048MNA#60 from Renesas Electronics is an 8 KB flash, 1 KB RAM RL78/G15 16-pin microcontroller with 8/10-bit ADC (7 channels), dual simplified I²C and SPI interfaces, UART, and 8-channel 16-bit timer array - designed for industrial temperature operation up to +125°C in HWQFN-16 package.

For engineers reviewing the R5F12048MNA#60 datasheet, R5F12048MNA#60 pinout, R5F12048MNA#60 application, or R5F12048MNA#60 equivalent, key selection criteria include its −40°C to +125°C industrial rating, 16-pin HWQFN (3 × 3 mm, 0.5-mm pitch) footprint, on-chip high-speed oscillator accuracy of ±1.0% (−20°C to +85°C), and integrated programmable clock/buzzer output (PCLBUZ0).

Technical Context

The R5F12048MNA#60 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and 1 MB address space. It supports multiple clock sources: high-speed on-chip oscillator (1–16 MHz, ±1.0% accuracy), low-speed on-chip oscillator (15 kHz), and external crystal (X1/X2, 1–12 MHz) or EXCLK input (1–16 MHz).

Its peripheral set includes a 7-channel 8/10-bit A/D converter with internal reference (0.815 V), two comparator channels (IVCMP0/IVCMP1), SAU0 serial array unit supporting CSI00/CSI01 (simplified SPI), IIC00/IIC01 (simplified I²C), and UART0 - all configurable via peripheral I/O redirection registers (PIOR).

FAQ

What is the operating temperature range specified for the R5F12048MNA#60?

The R5F12048MNA#60 is qualified for industrial operation from −40°C to +125°C (M-grade). This rating is confirmed in Table 1-2 of the datasheet and applies specifically to the "M" suffix in the part number, distinguishing it from A-grade (−40°C to +85°C) and G-grade (−40°C to +105°C) variants of the same device family.

Does the R5F12048MNA#60 support in-system programming without external hardware?

Yes, the R5F12048MNA#60 supports self-programming of its 8 KB code flash memory using on-chip debug resources via TOOL0/TOOLRxD/TOOLTxD pins. No external programmer is required for firmware updates, though the on-chip debug function must be enabled and configured per the RL78/G15 User's Manual - and should not be used in final mass-produced units per Renesas caution notice.

How many analog input channels does the R5F12048MNA#60 provide, and what is their resolution?

The R5F12048MNA#60 provides seven analog input channels (ANI0 through ANI6) with selectable 8-bit or 10-bit resolution. The ADC operates across the full 2.4–5.5 V supply range and includes an internal 0.815 V reference voltage source, enabling ratiometric measurements without external reference components.

What serial communication interfaces are integrated into the R5F12048MNA#60?

The R5F12048MNA#60 integrates UART0 (1 channel), simplified I²C (IIC00 and IIC01 - 2 channels), and simplified SPI (CSI00 and CSI01 - 2 channels) via its SAU0 serial array unit. These interfaces share pins with GPIO and are reconfigurable using the peripheral I/O redirection register (PIOR), allowing flexible peripheral assignment without PCB redesign.

Is the R5F12048MNA#60 pin-compatible with other RL78/G15 devices in the same package?

Yes, the R5F12048MNA#60 is pin-compatible with all other 16-pin HWQFN RL78/G15 variants, including R5F12047MNA#60 (4 KB flash) and R5F12048GNA#60 (G-grade temp). Pin functions, layout, and mechanical dimensions match exactly - enabling drop-in replacement for firmware or qualification upgrades without board changes.
