Renesas UPD78F0513DAGB-GAF-AX

Overview

UPD78F0513DAGB-GAF-AX from Renesas Electronics is an 8-bit single-chip microcontroller in the 78K0/KC2 family, featuring 64 KB on-chip Flash memory, 4 KB RAM, and a 16-bit timer/counter with PWM output capability. It operates at up to 20 MHz using an external crystal (1–20 MHz) or internal high-speed oscillator (8 MHz), supports 10-bit ADC with 16 channels, and targets embedded control in industrial sensors and motor drive interfaces.

For engineers reviewing the UPD78F0513DAGB-GAF-AX datasheet, UPD78F0513DAGB-GAF-AX pinout, UPD78F0513DAGB-GAF-AX application, or UPD78F0513DAGB-GAF-AX equivalent, key selection criteria include Flash endurance (100,000 erase/write cycles), operating voltage range (2.7–5.5 V), and support for I²C, UART, and CSI serial interfaces in a 64-pin LQFP package.

Technical Context

The UPD78F0513DAGB-GAF-AX implements the 78K0 CPU core with 16-bit address space, supporting 131 instructions including bit manipulation and multiply/divide operations. Its peripheral set includes a 16-bit reload timer (RTU), watchdog timer (WDT), and clock frequency divider (CKD) enabling flexible system clock configuration across multiple domains.

It integrates a 10-bit successive-approximation ADC with sample-and-hold circuitry, conversion time of 1.7 μs (max) at 20 MHz, and selectable reference sources (AVREF or internal 2.5 V). The device uses a single power supply (VDD/EVDD = 2.7–5.5 V) with separate analog ground (AVSS) and digital ground (VSS/EVSS) pins for noise isolation.

FAQ

What is the maximum operating frequency of the UPD78F0513DAGB-GAF-AX?

The UPD78F0513DAGB-GAF-AX supports a maximum system clock frequency of 20 MHz when driven by an external crystal oscillator (X1/X2) or the internal high-speed oscillator (with PLL enabled). At this speed, instruction execution achieves 10 million instructions per second (MIPS), and the 10-bit ADC maintains its specified 1.7 μs conversion time. The device also supports lower-frequency operation down to DC for ultra-low-power applications using STOP or HALT modes.

Does the UPD78F0513DAGB-GAF-AX include an integrated voltage regulator?

No, the UPD78F0513DAGB-GAF-AX does not include an on-chip voltage regulator. It requires externally supplied VDD/EVDD (2.7–5.5 V) and AVDD (2.7–5.5 V) with appropriate decoupling capacitors. Separate analog and digital power domains (AVDD/AVSS and VDD/VSS) must be independently filtered to meet ADC accuracy specifications. Renesas recommends 100 nF ceramic capacitors placed near each power pin pair.

Can the UPD78F0513DAGB-GAF-AX execute code while programming its own Flash memory?

Yes, the UPD78F0513DAGB-GAF-AX supports read-while-write (RWW) operation in specific Flash memory banks, enabling firmware updates without halting application execution. This capability relies on the built-in self-programming library (SPL) Type01, which manages bank switching and erase/write sequencing. The UPD78F0513DAGB-GAF-AX must be configured with proper wait-state settings and protected memory regions to avoid corruption during concurrent access.

What development tools are officially supported for the UPD78F0513DAGB-GAF-AX?

Renesas officially supports the QB-MINI2 on-chip debug emulator and the PG-FP5 Flash memory programmer for the UPD78F0513DAGB-GAF-AX. Software toolchains include the CC78K0 C compiler (Ver. 4.00) and RA78K0 assembler (Ver. 4.01), both integrated into the PM+ Ver. 6.30 IDE. Application notes U17516E (Self Programming) and U17739E (Flash Programming) provide validated procedures for production programming and field updates of the UPD78F0513DAGB-GAF-AX.

Is the UPD78F0513DAGB-GAF-AX qualified for automotive applications?

No, the UPD78F0513DAGB-GAF-AX is classified as a "Standard" quality grade device per Renesas documentation, intended for industrial, office, and consumer applications - not automotive or safety-critical systems. It lacks AEC-Q100 qualification, extended temperature range (-40°C to +85°C only), and automotive-specific failure-in-time (FIT) data. For automotive use, Renesas recommends the RL78/F1x or RH850 families, which are explicitly qualified to AEC-Q100 Grade 2 or higher.
