It operates at up to 20 MHz and supports industrial temperature range (−40°C to +85°C) in a 48-pin LQFP package. It is used in motor control, industrial automation, and building management systems.
For engineers reviewing the UPD78F1814AGAA2-GAM-E2-G datasheet, UPD78F1814AGAA2-GAM-E2-G pinout, UPD78F1814AGAA2-GAM-E2-G application, or UPD78F1814AGAA2-GAM-E2-G equivalent, key selection considerations include Flash endurance (100,000 write/erase cycles), CAN bus timing compliance, ADC sampling rate (1.25 MSPS), and support for on-chip debug via QB-MINI2.
Technical Context
The UPD78F1814AGAA2-GAM-E2-G implements the 78K0R CPU core with 16-bit architecture, Harvard memory organization, and instruction set compatible with earlier 78K0 devices. It integrates a dedicated CAN controller supporting both standard and extended frames, with programmable bit timing and automatic retransmission.
Its peripheral set includes three 16-bit timer arrays (each with capture/compare/PWM functions), a 12-channel 12-bit ADC with hardware-triggered conversion, and dual serial interfaces (UART and I²C) with clock synchronization logic. The device uses on-chip voltage regulator (REGC pin) for internal core supply and supports low-power modes including HALT and STOP.

FAQ
What is the maximum operating frequency of the UPD78F1814AGAA2-GAM-E2-G?
The UPD78F1814AGAA2-GAM-E2-G operates at a maximum system clock frequency of 20 MHz. This frequency is supported across its full industrial temperature range (−40°C to +85°C) and supply voltage range (2.7 V to 5.5 V). The internal PLL allows flexible clock source configuration, including external crystal (1–20 MHz), ceramic resonator, or internal high-speed oscillator. At 20 MHz, the CPU executes instructions at approximately 10 MIPS due to its 3-stage pipeline architecture.
Does the UPD78F1814AGAA2-GAM-E2-G include an integrated CAN transceiver?
No, the UPD78F1814AGAA2-GAM-E2-G integrates only the CAN protocol controller (CAN 2.0B compliant), not the physical layer transceiver. It requires an external high-speed CAN transceiver (e.g., TJA1042, SN65HVD230) connected to its CAN_TX and CAN_RX pins. The controller supports all CAN 2.0B features including identifier masking, message filtering, automatic retransmission, and error frame handling - but physical bus driving and differential signaling must be handled externally.
What debug interface does the UPD78F1814AGAA2-GAM-E2-G support?
The UPD78F1814AGAA2-GAM-E2-G supports Renesas' single-wire debug (SWD) interface via pins P10 (SWCLK) and P11 (SWDIO), compatible with the QB-MINI2 on-chip debug emulator. This interface enables full-speed debugging, real-time register and memory inspection, flash programming, and breakpoint setting without halting peripheral operation. No JTAG header is required, reducing PCB footprint and simplifying development setup.
How is the internal voltage regulator configured on the UPD78F1814AGAA2-GAM-E2-G?
The UPD78F1814AGAA2-GAM-E2-G uses the REGC pin to connect an external 1.0 μF ceramic capacitor, which stabilizes the internal 1.8 V core voltage regulator. This regulator powers the CPU core and internal logic independently of the main VDD supply (2.7–5.5 V), improving noise immunity and enabling stable operation across wide input voltage ranges. The REGC capacitor must be placed within 3 mm of the REGC pin with low-inductance routing for reliable startup and transient response.
Is the UPD78F1814AGAA2-GAM-E2-G qualified for automotive applications?
No, the UPD78F1814AGAA2-GAM-E2-G is rated for industrial-grade operation (−40°C to +85°C) and classified as a "Standard" quality grade per Renesas documentation. It is not AEC-Q100 qualified and lacks automotive-specific features such as extended temperature range (−40°C to +125°C), enhanced ESD protection, or fault-tolerant CAN implementations. For automotive use, Renesas recommends the RL78/F14 or RH850/F1L families instead.
