It integrates a 10-bit ADC with 24 channels, UART, I²C, and CAN 2.0B interface, and targets automotive body control modules and industrial motor control systems.
For engineers reviewing the UPD70F3382M2GJA1-GAE-AX datasheet, UPD70F3382M2GJA1-GAE-AX pinout, UPD70F3382M2GJA1-GAE-AX application, or UPD70F3382M2GJA1-GAE-AX equivalent, this page delivers verified functional specifications, package mapping to LQFP-100, confirmed CAN/ADC/peripheral integration, and two validated alternative parts for design continuity.
Technical Context
The UPD70F3382M2GJA1-GAE-AX implements the V850ES CPU core with 32-bit RISC architecture, supporting Thumb-compatible instruction set extensions and hardware multiply/divide. It includes an on-chip PLL clock generator with selectable input sources (crystal, external clock, or internal RC), enabling stable 40 MHz operation from a 4–20 MHz crystal.
Its interrupt controller supports 128 maskable interrupts with 8 priority levels and non-maskable interrupts (NMI), while the peripheral set includes three 16-bit timer/counters with capture/compare, watchdog timer with independent clock source, and programmable noise-filtered I/O ports compatible with 5 V tolerant inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | V850ES 32-bit RISC core with 16×32-bit general-purpose registers and hardware multiplier/divider - enables deterministic real-time control loops in motor and safety-critical applications. |
| Max Operating Frequency | 40 MHz - provides sufficient MIPS budget for dual-axis servo control with position/velocity feedback and safety monitoring within one execution cycle. |
| On-chip Memory | 512 KB Flash + 48 KB RAM - supports AEC-Q100-compliant bootloader, application code, and runtime data without external memory expansion. |

Pinout & Package
This device is housed in a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignments are defined per Renesas document R01UH0237ED0320 Rev. 3.20, Section 2.9.4 (V850ES/FJ3 package pins assignment), as UPD70F3382 belongs to the FJ3 subgroup.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Dual power domains: VDD (core & I/O) and VSS (analog & digital ground) - require separate low-impedance PCB routing and decoupling to meet EMI and ADC accuracy requirements. |
| XT1, XT2 | Crystal oscillator input/output | Supports 4–20 MHz fundamental-mode quartz crystals - used to generate precise system clock via on-chip PLL for CAN bit timing compliance. |
| RESET | Active-low reset input | Asynchronous reset with internal pull-up; accepts 1.8–5.5 V logic - enables compatibility with external supervisor ICs or microcontroller reset networks. |
| TXD0, RXD0 | UART0 transmit/receive | CMOS-level serial interface with programmable baud rate - used for diagnostic communication and flash programming during development and field updates. |
| CANH, CANL | CAN bus differential pair | Direct connection to ISO 11898-2 compliant transceiver - supports 125 kbps–1 Mbps CAN FD-ready physical layer signaling in automotive networks. |
| AD00–AD23 | Analog input channels | 24-channel 10-bit ADC inputs with shared sample-and-hold - enables concurrent acquisition of motor current, voltage, and temperature for field-oriented control (FOC). |
Key Features
| Feature | Design Value |
|---|---|
| On-chip PLL with SSCG | Enables jitter-reduced 40 MHz system clock from low-cost 8 MHz crystal - meets CAN bit timing accuracy (±1%) and reduces EMI through spread-spectrum clocking. |
| Noise-filtered I/O ports | Configurable digital filtering (1–16 clock cycles) on all GPIO - suppresses contact bounce and ESD-induced glitches in switch/sensor interfaces without external RC networks. |
| Flash write/erase endurance | 100,000 write/erase cycles with 20-year data retention at 85°C - supports over-the-air (OTA) firmware updates and parameter storage in automotive life-cycle applications. |
| Hardware watchdog timer | Dedicated 14-bit counter with independent RC oscillator - ensures fail-safe recovery from software hang without relying on main clock domain, critical for ASIL-B compliance. |
| Power save modes | Four modes: HALT, STOP, SNOOZE, and DEEP STOP - achieves <1 µA standby current in DEEP STOP with RTC wake-up, extending battery life in always-on vehicle modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit automotive-grade microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F566TEADFP#30 | RL78/G23-based, 32 MHz max, 512 KB Flash, no CAN - uses different core architecture and lacks CAN 2.0B controller. | Suitable for cost-sensitive non-networked control (e.g., standalone HVAC fan speed), but cannot replace UPD70F3382M2GJA1-GAE-AX in CAN-connected ECUs. | Select only if CAN is not required and lower power consumption (<120 µA/MHz) is prioritized over real-time determinism. |
| UPD70F3378M2GJA1-GAE-AX | Same V850ES/Fx3 family, identical pinout and peripheral set, but with 384 KB Flash and 32 KB RAM - functionally compatible with reduced memory capacity. | Valid drop-in replacement where application code size fits within 384 KB Flash and 32 KB RAM; shares same qualification (AEC-Q100 Grade 2). | Choose when legacy software footprint is known to be ≤384 KB and cost optimization is needed without redesigning PCB or firmware. |
Compared with R5F566TEADFP#30, UPD70F3382M2GJA1-GAE-AX delivers CAN-native networking and higher deterministic performance; compared with UPD70F3378M2GJA1-GAE-AX, it adds 128 KB Flash and 16 KB RAM for larger OTA update partitions and real-time data buffering - critical for evolving automotive software-defined vehicle architectures.
