FAQ
What is the maximum operating frequency of the R5F61648AD50FPV#ZB?
The R5F61648AD50FPV#ZB operates at a maximum CPU frequency of 50 MHz, achieved via its internal PLL using an external crystal (1–20 MHz range). This frequency is fully supported across the specified industrial temperature range (−40°C to +85°C) and supply voltage (3.0 V to 3.6 V), enabling consistent real-time performance in motor control and automation applications where timing predictability is critical. The R5F61648AD50FPV#ZB achieves sub-20 ns instruction cycle times under these conditions.
Does the R5F61648AD50FPV#ZB include on-chip Flash memory, and what is its capacity?
Yes, the R5F61648AD50FPV#ZB integrates 512 KB of on-chip Flash memory with 4 KB of dedicated boot ROM. This Flash supports up to 100,000 write/erase cycles and includes lock-bit protection to prevent unauthorized readout or modification. The memory map is aligned for efficient C-language execution and supports in-application programming (IAP), allowing field firmware updates without external programmers - a key capability for deployed R5F61648AD50FPV#ZB systems.
Which communication interfaces are integrated into the R5F61648AD50FPV#ZB?
The R5F61648AD50FPV#ZB integrates two Serial Communications Interfaces (SCI0 and SCI1), each supporting asynchronous (UART), clock-synchronous (SPI-like), and IrDA modes, plus a dedicated Inter-Equipment Bus (IEBus) interface compliant with NEC's IEBus specification. These interfaces operate independently with separate baud rate generators and DMA-capable buffers. No external transceivers are required for IEBus or RS-232-level SCI operation when paired with appropriate level-shifting components - simplifying design for R5F61648AD50FPV#ZB-based industrial networks.
What timer resources does the R5F61648AD50FPV#ZB provide for motor control applications?
The R5F61648AD50FPV#ZB provides a 16-channel Timer Pulse Unit (TPU) with independent compare/capture registers, two 8-bit timers (TMR), and a windowed watchdog timer (WDT). The TPU supports complementary PWM output with programmable dead-time insertion, edge-aligned and center-aligned modes, and synchronous reload - all essential for driving 3-phase inverter bridges. These resources are directly accessible by the R5F61648AD50FPV#ZB CPU without software overhead, ensuring precise timing control in motor control firmware.
Is the R5F61648AD50FPV#ZB pin-compatible with other members of the H8SX/1648A Group?
Yes, the R5F61648AD50FPV#ZB shares identical pin assignment, electrical characteristics, and memory map with other LQFP-144 variants in the H8SX/1648A Group (e.g., R5F61648AD64FPV#ZB and R5F61648AD50FPV#W2), differing only in maximum clock rating or package finish. This allows hardware reuse across performance tiers and manufacturing processes. Firmware developed for R5F61648AD50FPV#ZB runs unchanged on these variants, provided clock initialization and thermal management align with the target device's specifications.
