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 requiring deterministic real-time response.
For engineers reviewing the UPD78F1826GAA2-GAM-G datasheet, UPD78F1826GAA2-GAM-G pinout, UPD78F1826GAA2-GAM-G application, or UPD78F1826GAA2-GAM-G equivalent, key selection criteria include Flash endurance (100k write/erase cycles), CAN bus timing compliance, ADC sampling rate (1.25 MSPS), and availability of hardware multiplier/divider for servo loop computation.
Technical Context
The UPD78F1826GAA2-GAM-G implements the 78K0R CPU core with 16-bit ALU, 24-bit address space, and Harvard architecture with separate instruction/data buses. It integrates a 32-channel 12-bit successive-approximation ADC with programmable sampling time and window comparator function.
Its peripheral set includes two 16-bit timer arrays (each with four channels supporting PWM, input capture, and one-shot output), three serial interfaces (UART, I²C, and CAN 2.0B), and a 16-bit hardware multiplier/divider operating in ≤3 cycles. The device supports boot ROM-based self-programming and secure flash protection via lock bits.

No, the UPD78F1826GAA2-GAM-G implements only CAN 2.0B protocol compliant with ISO 11898-1:2003. It supports standard (11-bit) and extended (29-bit) identifiers, bit rates up to 1 Mbps, and 32 message objects with hardware FIFO buffering. CAN FD features such as flexible data-rate, longer payloads, and CRC enhancements are not supported in this device.
How much Flash endurance does the UPD78F1826GAA2-GAM-G provide?
The UPD78F1826GAA2-GAM-G guarantees 100,000 write/erase cycles for its 256 KB on-chip Flash memory, with data retention specified for 10 years at +85°C. Flash sectors can be erased independently (1 KB or 4 KB blocks), and programming is performed in byte, word, or long-word units. Endurance is validated per JEDEC JESD22-A117 standard.
Is the UPD78F1826GAA2-GAM-G qualified for automotive applications?
No, the UPD78F1826GAA2-GAM-G is rated for industrial temperature range (−40°C to +85°C) and classified as "Standard" quality grade per Renesas documentation. It is not AEC-Q100 qualified and is not recommended for safety-critical automotive systems. For automotive use, Renesas offers the RL78/F14 or RH850 families with full AEC-Q100 Grade 2/1 qualification.
What debug interface does the UPD78F1826GAA2-GAM-G support?
The UPD78F1826GAA2-GAM-G supports on-chip debugging via the dedicated 5-pin SWJ-DP (Serial Wire JTAG Debug Port) interface, compatible with Renesas E2 emulator and third-party tools supporting ARM CoreSight SWD.
