Product details
Overview
UPD78F0535AGC-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 using an internal high-speed oscillator or external crystal, supports 10-bit ADC with 16 channels, and targets embedded control in industrial sensors and motor drive interfaces.
For engineers reviewing the UPD78F0535AGC-GAL-AX datasheet, UPD78F0535AGC-GAL-AX pinout, UPD78F0535AGC-GAL-AX application, or UPD78F0535AGC-GAL-AX equivalent, this page delivers verified technical context, package mapping, functional pin roles, real-world use cases, and validated alternative options for design-in and supply continuity.
Technical Context
The UPD78F0535AGC-GAL-AX implements the 78K0 CPU core with 16-bit addressing, supporting 131 instructions including bit manipulation and multiply/divide operations. It integrates a 10-bit successive-approximation ADC with sample-and-hold, programmable gain amplifier input, and conversion time of 1.2 μs per channel at 20 MHz system clock.
On-chip peripherals include three 16-bit timers (two with complementary PWM outputs), UART, CSI, I2C-compatible serial interface, watchdog timer with independent clock source, and low-voltage detection circuit with reset generation. All peripherals are synchronized to the same system clock domain without separate clock gating controls.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LGSP#V0 | RL78/G13 core; 32 KB Flash, 4 KB RAM, lower max clock (24 MHz), no integrated PGA | Targets cost-sensitive consumer appliances where ADC precision is less critical than ultra-low power | Select when prioritizing sub-100 μA standby current and toolchain compatibility with RL78 ecosystem |
| UPD78F0527AGC-GAL-AX | Same 78K0/KE2 family; 48 KB Flash, identical peripheral set except reduced ADC channels (8 vs. 16) | Suitable for simpler motor control or lighting systems requiring fewer analog inputs | Choose for pin-compatible migration path when application requires only 8 ADC channels and smaller code footprint |
Compared with UPD78F0535AGC-GAL-AX, R5F100LGSP#V0 offers superior energy efficiency but sacrifices analog front-end flexibility, while UPD78F0527AGC-GAL-AX provides identical timing and I/O behavior with reduced memory-making it ideal for derivative designs scaling down feature count without layout changes.

FAQ
What is the maximum operating frequency of the UPD78F0535AGC-GAL-AX?
The UPD78F0535AGC-GAL-AX supports a maximum system clock frequency of 20 MHz. This can be achieved using either the internal high-speed oscillator (with ±1% accuracy after calibration) or an external crystal/resonator in the 1–20 MHz range. The CPU instruction cycle time is 50 ns at 20 MHz, enabling deterministic execution of time-critical control loops.
Does the UPD78F0535AGC-GAL-AX include hardware support for PWM generation?
Yes, the UPD78F0535AGC-GAL-AX integrates three 16-bit timer modules, two of which support complementary PWM output with programmable dead-time insertion. These timers can generate up to six independent PWM signals with 16-bit resolution and center-aligned or edge-aligned modes, making UPD78F0535AGC-GAL-AX suitable for precise motor phase control and LED dimming applications.
How many analog input channels does the UPD78F0535AGC-GAL-AX ADC support?
The UPD78F0535AGC-GAL-AX features a 10-bit successive-approximation ADC with 16 selectable analog input channels (AN0 through AN15), mapped across Port 2 pins. Each channel supports software-triggered or timer-triggered conversion, and the ADC includes a built-in sample-and-hold circuit and programmable gain amplifier with 1×, 2×, 4×, or 8× settings.
Is the UPD78F0535AGC-GAL-AX pin-compatible with other members of the 78K0/KE2 family?
Yes, the UPD78F0535AGC-GAL-AX shares the same 100-pin LQFP package and pinout with other 78K0/KE2 devices including UPD78F0531AGC-GAL-AX through UPD78F0537AGC-GAL-AX. This allows direct substitution within the same family for memory or peripheral scaling-provided software is adapted to match Flash size and peripheral enable registers.
