Product details
Overview
UPD78F1186AGJ-GAE-AX from Renesas Electronics is a 16-bit single-chip microcontroller in the 78K0R/KE3 family, featuring 128 KB on-chip Flash memory, 8 KB RAM, and integrated peripherals including 10-bit ADC (16 channels), UART, I²C, and timer modules. It operates at up to 20 MHz with supply voltage range 2.7–5.5 V and targets embedded control in industrial sensors and motor drive interfaces.
For engineers reviewing the UPD78F1186AGJ-GAE-AX datasheet, UPD78F1186AGJ-GAE-AX pinout, UPD78F1186AGJ-GAE-AX application, or UPD78F1186AGJ-GAE-AX equivalent, key selection criteria include Flash endurance (100k write/erase cycles), operating temperature range (−40°C to +85°C), and support for on-chip debug via single-wire interface - all confirmed in Renesas U17854EJ9V0UD User's Manual.
Technical Context
The UPD78F1186AGJ-GAE-AX implements the 78K0R CPU core with 16-bit architecture, Harvard memory organization, and instruction set compatible with earlier 78K0 devices. It integrates a 10-bit successive-approximation ADC with sample-and-hold, programmable gain amplifier input option, and conversion time of 1.2 μs per channel.
Peripherals include three 16-bit timer/counters (one with complementary PWM output), two serial interface controllers (UART and I²C), and a watchdog timer with independent clock source. The device supports low-power modes (HALT, STOP) with wake-up via external interrupt or peripheral event.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 78K0R 16-bit CPU with 20 MHz max operation - enables deterministic real-time control loops with sub-μs interrupt latency. |
| Flash Memory | 128 KB on-chip Flash with 100k write/erase cycles - supports field firmware updates without external memory. |
| RAM Size | 8 KB on-chip RAM - sufficient for stack, heap, and real-time data buffers in sensor fusion or PID control applications. |
| ADC Resolution | 10-bit SAR ADC with 16 input channels - delivers ±1 LSB INL for precision analog monitoring in industrial transducers. |
| Supply Voltage | 2.7 V to 5.5 V operation - allows direct interfacing with 3.3 V or 5 V logic systems without level-shifting. |
| Operating Temp | −40°C to +85°C - qualified for use in factory automation enclosures and outdoor metering equipment. |
| Package Type | 64-pin LQFP (10 mm × 10 mm, 0.5 mm pitch) - provides robust thermal performance and PCB layout compatibility with legacy 78K0R designs. |
Pinout & Package
The UPD78F1186AGJ-GAE-AX is housed in a 64-pin LQFP package (JEDEC MS-026AC) with exposed thermal pad. Pin assignments follow the 78K0R/KE3 standard layout defined in Renesas User's Manual U17854EJ9V0UD Section 1.5 and Figure 1.5-1 (top view).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, EVDD | Power supply inputs | Dual power domains: VDD for digital core/I/O, EVDD for analog peripherals - enables noise isolation between logic and ADC sections. |
| VSS, EVSS | Ground returns | Separate digital and analog ground pins - required for stable 10-bit ADC performance and EMI suppression. |
| P00–P06 | Port 0 bidirectional I/O | Configurable as general-purpose I/O or alternate functions (e.g., UART TX/RX, timer outputs) - supports flexible peripheral mapping. |
| P10–P17 | Port 1 bidirectional I/O | Includes dedicated ADC input channels (AN0–AN7) and external interrupt inputs - simplifies analog front-end and event-driven sensing. |
| RESET | Active-low reset input | Asynchronous reset with internal pull-up - ensures reliable initialization during power-up or brownout recovery. |
| FLMD0 | Flash mode select | Controls boot mode (ROM vs. user program) at power-on - critical for secure firmware loading and bootloader configuration. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip Debug Interface | Single-wire debug (SWD) with full breakpoint and watchpoint support - enables in-system debugging without JTAG header footprint. |
| ADC with PGA | Programmable gain amplifier (PGA) integrated before ADC input - eliminates external signal conditioning for low-level sensor signals (e.g., thermocouples). |
| PWM Output | Complementary PWM with dead-time insertion on Timer Array Unit - directly drives half-bridge MOSFETs in motor control without external gate drivers. |
| Low-Power Modes | HALT (CPU stop, peripherals active) and STOP (all clocks halted except WDT) - extends battery life in portable instrumentation. |
| Flash Security | Flash protection lock bits prevent read-out and unauthorized reprogramming - meets basic firmware IP protection requirements. |
Applications
| Industrial Sensor Node | Motor Drive Interface |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100PLGFB | RL78/G13 core, 128 KB Flash, 12 KB RAM, same 64-pin LQFP - higher RAM, lower power (0.55 μA STOP mode), but no PGA on ADC. | Lacks integrated programmable gain amplifier - requires external op-amp stage for mV-range sensor signals. | Select when ultra-low power or enhanced interrupt nesting is prioritized over analog front-end integration. |
| UPD78F1154AGC-GAD-AX | Same 78K0R/KE3 family, 96 KB Flash, 6 KB RAM, identical peripheral set - smaller Flash/RAM, same pinout and register map. | Reduced memory capacity limits complex communication stacks or multi-sensor fusion algorithms. | Select when cost sensitivity outweighs need for 128 KB Flash and extended data buffering capability. |
Compared with UPD78F1186AGJ-GAE-AX, R5F100PLGFB offers superior energy efficiency but sacrifices analog signal conditioning flexibility, while UPD78F1154AGC-GAD-AX provides pin-compatible scalability down for simpler control tasks - both require validation of Flash programming toolchain compatibility.
