FAQ
What is the maximum operating frequency of the UPD70F3572GBA1-GAH-AX?
The UPD70F3572GBA1-GAH-AX operates at a maximum frequency of 40 MHz, achieved via its internal PLL driven by an external crystal (1–20 MHz) on the XIN/XOUT pins. This frequency enables sub-microsecond interrupt latency and consistent instruction timing for hard real-time control loops in the UPD70F3572GBA1-GAH-AX.
Does the UPD70F3572GBA1-GAH-AX support in-system programming?
Yes, the UPD70F3572GBA1-GAH-AX supports in-system programming via its on-chip debug (OCD) interface using Renesas' PG-FP5 programmer. It also enables code flash self-programming through dedicated library functions, allowing firmware updates without external tools - a core capability of the UPD70F3572GBA1-GAH-AX.
How many DMA channels does the UPD70F3572GBA1-GAH-AX include?
The UPD70F3572GBA1-GAH-AX integrates a 4-channel DMA controller with priority arbitration and trigger factor register (DTFR) support. Each channel can be independently configured for memory-to-peripheral, peripheral-to-memory, or memory-to-memory transfers - a key performance feature of the UPD70F3572GBA1-GAH-AX.
Is the UPD70F3572GBA1-GAH-AX pin-compatible with other V850E2/Fx4-L family members?
Yes, the UPD70F3572GBA1-GAH-AX shares the same 80-pin LQFP package and pinout with UPD70F3571GBA1-GAH-AX and UPD70F3573GBA1-GAH-AX. This allows hardware reuse across variants differing only in flash/RAM size - a documented compatibility feature of the UPD70F3572GBA1-GAH-AX family.
What is the endurance rating of the data flash in the UPD70F3572GBA1-GAH-AX?
The data flash memory in the UPD70F3572GBA1-GAH-AX is rated for 100,000 write/erase cycles and guarantees data retention for 20 years at 85°C. This specification is validated per Renesas' qualification standards and applies directly to the UPD70F3572GBA1-GAH-AX device.
