FAQ
What is the maximum operating frequency supported by DF71323AD80FPV?
The DF71323AD80FPV supports a maximum operating frequency of 40 MHz, achieved using its on-chip Clock Pulse Generator with PLL. This frequency is derived from an external 8 MHz crystal connected to CLKIN, and it defines the upper limit for instruction execution speed, peripheral timing, and real-time response capability in applications such as motor control and industrial sensing where deterministic latency matters.
Does DF71323AD80FPV include on-chip flash or ROM memory?
DF71323AD80FPV contains 128 KB of mask-programmed ROM, not flash memory. This ROM is programmed during wafer fabrication and cannot be reprogrammed in-system. It provides secure, tamper-resistant storage for production firmware and is optimized for reliability in fixed-function embedded applications like energy meters and PLC modules where field updates are unnecessary.
What debug interface does DF71323AD80FPV support?
DF71323AD80FPV supports IEEE 1149.1 JTAG boundary-scan and on-chip debugging via its dedicated TDI/TDO/TCK/TMS/TRST pins. This enables full visibility into CPU state, register contents, and memory during development, and supports real-time trace without halting program execution - critical for validating timing-critical control loops in the DF71323AD80FPV-based systems.
Is DF71323AD80FPV qualified for automotive applications?
No, DF71323AD80FPV is rated as a Renesas Standard-grade device intended for commercial and industrial applications such as office equipment, test instruments, and factory automation. It is not qualified to AEC-Q100 or certified for automotive use. For automotive designs, Renesas recommends SH72xx or RH850 family devices explicitly specified for transportation equipment.
What is the function of the OSCCR register in DF71323AD80FPV?
The Oscillation Stop Detection Control Register (OSCCR) in DF71323AD80FPV enables hardware detection of crystal oscillator failure. When enabled, it triggers a non-maskable interrupt if the external resonator stops oscillating - allowing the DF71323AD80FPV to initiate safe shutdown or fallback behavior in mission-critical systems such as industrial controllers where clock integrity directly impacts functional safety.
