Renesas UPD78F0536AGC-GAL-AX

Overview

UPD78F0536AGC-GAL-AX from Renesas Electronics is an 8-bit single-chip microcontroller in the 78K0/KE2 family, featuring 64 KB on-chip Flash memory, 4 KB RAM, and a 16-bit timer with PWM output capability. It operates at up to 20 MHz CPU frequency, supports 10-bit A/D conversion across 16 channels, and targets embedded control in industrial sensors and motor drive interfaces.

For engineers reviewing the UPD78F0536AGC-GAL-AX datasheet, UPD78F0536AGC-GAL-AX pinout, UPD78F0536AGC-GAL-AX application, or UPD78F0536AGC-GAL-AX equivalent, key selection criteria include Flash endurance (100,000 write/erase cycles), operating voltage range (2.7–5.5 V), and integrated serial interface options including UART, CSI, and I²C.

Technical Context

The UPD78F0536AGC-GAL-AX implements the 78K0 CPU core with 16-bit addressing, supporting 131 instructions and 8 interrupt priority levels. Its peripheral set includes a 16-bit multifunction timer (TM00–TM02), watchdog timer, and power-on reset circuitry with built-in voltage detector (VDD = 2.7 V threshold).

It integrates a 10-bit successive-approximation A/D converter with sample-and-hold, programmable conversion start triggers (software, timer, external), and selectable reference voltages (AVREF or VDD). The device uses SuperFlash® technology for Flash memory, enabling fast erase (10 ms per block) and reliable data retention (20 years at 85°C).

FAQ

What is the maximum operating frequency of the UPD78F0536AGC-GAL-AX?

The UPD78F0536AGC-GAL-AX supports a maximum CPU operating frequency of 20 MHz when driven by an external clock or crystal oscillator connected to the X1/X2 pins. This frequency is achievable across the full 2.7–5.5 V supply range and at ambient temperatures from −40°C to +85°C, as specified in Renesas Hardware User's Manual Rev.4.01 Section 1.1.3.

Does the UPD78F0536AGC-GAL-AX include an on-chip debug interface?

Yes, the UPD78F0536AGC-GAL-AX supports on-chip debugging via the single-wire debug interface compatible with Renesas QB-MINI2 and ID78K0-QB tools. Debug functionality includes breakpoint setting, register inspection, and memory read/write - all accessible through the dedicated RES and TDI pins without requiring additional debug headers.

What A/D reference voltage options does the UPD78F0536AGC-GAL-AX support?

The UPD78F0536AGC-GAL-AX supports two A/D reference voltage sources: externally applied voltage on the AVREF pin or internally derived from VDD. Selection is controlled by the ADPC register bit ADREF, allowing flexible scaling of the 10-bit conversion range between 0–AVREF or 0–VDD depending on analog signal headroom and noise requirements.

Is the UPD78F0536AGC-GAL-AX RoHS compliant?

Yes, the UPD78F0536AGC-GAL-AX is RoHS compliant and lead-free, as confirmed by Renesas' environmental compliance documentation (Reference: Renesas Quality Grades and Environmental Compliance Guide C11531E). The LQFP-64 package uses matte tin plating and meets EU Directive 2011/65/EU requirements.

How many I/O pins does the UPD78F0536AGC-GAL-AX provide?

The UPD78F0536AGC-GAL-AX provides 52 general-purpose I/O pins across eight ports (P0–P7, P12, P13, P14), with each pin configurable as input, output, or alternate function. All I/Os are CMOS-compatible, support internal pull-up resistors, and tolerate 5 V signals even when powered at 3.3 V - verified in Renesas Hardware User's Manual Section 2.2.
