R5F524TAADFF: 5 V Motor Silicon In LQFP48

The R5F524TAADFF is a member of Renesas’ RX24T group: an RXv2 32-bit CISC core at 80 MHz on 5 V, with 256 KB code array and 64 KB runtime memory in a LQFP48. A services page schedules the bench work and returns a verified R5F524TAADFF image.

Peripheral Set

The RX24T silicon in the R5F524TAADFF is built for motors: MTU3 complementary PWM, a GPT unit and a 12-bit ADC near 0.5 us. What distinguishes the R5F524TAADFF is its peripheral mix aimed at drives: MTU3 PWM, GPT timers, a fast 12-bit ADC and a 10-bit DAC. An R8C recover note documents the same vendor’s older line using a comparable ID gate.

Where The Read Protection Lives

The R5F524TAADFF protects its code with a debug ID code in the option-setting memory, compared against a value the debugger presents. Access to the R5F524TAADFF is gated by an ID code in the option area, checked each time the background debug interface connects. Our protection-bypass guide sets out the general route for Renesas and ARM parts alike.

Flash And Working Memory

Three memory types share the R5F524TAADFF: 256 KB code array for the program, an 8 KB data flash for EEPROM emulation, and 64 KB runtime memory. The R5F524TAADFF splits storage into 256 KB code array, a dedicated 8 KB data flash and 64 KB runtime memory for runtime state. The LPC2468 external-bus case shows the same hazard on an older ARM part with off-chip code.

Reporting And Hand-Off

Delivery is one Intel HEX at the true addresses, a binary per region, and a report listing the ID state and data-flash counts. Customers get an Intel HEX merging all regions at real addresses, separate binaries, and a short report for the R5F524TAADFF LQFP48. Our R5F524T8ADFM coverage pairs with this R5F524TAADFF page for the full group picture.

Bench Routine

We read 256 KB code array, then the 8 KB data flash, then the option memory, then a live RAM snapshot, and repeat for a checksum. The capture order on the R5F524TAADFF is code flash, data flash, option memory, then a confirming second pass on the 5 V rail.

Where a live LQFP48 board is supplied we trace the serial lines before removing power from the R5F524TAADFF.

The 256 KB code array on the R5F524TAADFF is read at the true addresses, not a relocated image a tool might invent.

Where decapsulation was needed the bare die of the R5F524TAADFF is photographed before the lid is fully removed.

The R5F524TAADFF is photographed next to a scale so the package size is unambiguous in the archive.

We keep the bench notes with the order so the R5F524TAADFF protection level is never lost between reads.

We record the supply rail used on the LQFP48, because the R5F524TAADFF flash timing is sensitive to voltage.

A small reference card travels with the R5F524TAADFF so the bench knows the expected die orientation.

For the LQFP48 R5F524TAADFF we confirm the pin one mapping against the data sheet before closing the job.

We keep the R5F524TAADFF away from strong fields on the bench, since flash can be disturbed by magnets.

The 48-pin R5F524TAADFF is logged against its order code so a repeat job reuses the same bench setup.

Our report flags any external memory the LQFP48 board carried, since the R5F524TAADFF image may span parts.

The RXv2 32-bit CISC @80 MHz, 5 V clock source is noted for the R5F524TAADFF, because a rebuild with the wrong PLL will not start.

The report includes the option or signature contents so the R5F524TAADFF lock can be re-applied if required.

The RXv2 32-bit CISC @80 MHz, 5 V on the R5F524TAADFF runs the recovered code in place, so the cover report notes the boot setup for a spare LQFP48.

A LQFP48 R5F524TAADFF sent cold in foam reads more reliably than one that travelled powered and warm.

The recovered files for the R5F524TAADFF are named by order number, never by the chip marking alone.

The customer receives the files with a short note on reflashing the LQFP48 without tripping the code lock again.

We confirm the 48-pin count against the marking so the recovered R5F524TAADFF netlist lines up with the board.

The LQFP48 outline of the R5F524TAADFF matches other group members, so the marking confirms the exact die fitted.

We separate the 256 KB code array from working memory in the archive, since mixing them hides the code lock state.
