FAQ
What is the maximum operating frequency of the R5S72620W144FP#U0?
The R5S72620W144FP#U0 operates at a maximum CPU frequency of 120 MHz when using the on-chip PLL with an external 20 MHz crystal. This frequency is sustained across the full −40°C to +85°C temperature range and 3.0 V to 3.6 V supply voltage, as verified in the Electrical Characteristics section of the R01UH0134EJ0400 Hardware Manual.
Does the R5S72620W144FP#U0 include an on-chip USB transceiver?
Yes, the R5S72620W144FP#U0 integrates a full-speed USB 2.0 transceiver compliant with USB Specification Revision 2.0. It supports device-mode operation only, requires no external PHY, and uses dedicated USB_DP and USB_DM pins with internal termination and pull-up control managed by the USB control registers.
What is the Flash memory endurance specification for the R5S72620W144FP#U0?
The R5S72620W144FP#U0 specifies 100,000 write/erase cycles for its 1 MB on-chip Flash memory, as documented in Section 8 "Electrical Characteristics" of the R01UH0134EJ0400 Hardware Manual. Each sector can be erased independently, and ECC circuitry detects and corrects single-bit errors during read operations.
Is the R5S72620W144FP#U0 qualified for automotive applications?
The R5S72620W144FP#U0 is classified as a Standard-grade Renesas product, intended for office equipment, industrial robots, and communications equipment-not for safety-critical automotive powertrain or chassis systems. Its −40°C to +85°C operating range meets AEC-Q100 Grade 3 requirements, but it lacks ASIL certification and is not approved for high-quality automotive applications per Renesas' quality grade policy.
How many CAN controllers does the R5S72620W144FP#U0 integrate?
The R5S72620W144FP#U0 integrates three independent CAN 2.0B-compatible controllers, each with dedicated message RAM, acceptance filtering, and transmit/receive FIFOs. These controllers operate concurrently without shared resources, enabling simultaneous communication on separate CAN buses in body control or diagnostic gateway applications.
