This capability is implemented in silicon per R01DS0190EJ0130 Rev.1.30 and requires no external PHY - the R5F51111AGNE#2A uses its native USB0_DP and USB0_DM pins for dual-role connectivity.
What are the analog capabilities of the R5F51111AGNE#2A?
The R5F51111AGNE#2A includes a 12-bit successive-approximation A/D converter with up to 14 input channels and a minimum conversion time of 1.0 µs at 32 MHz ADCLK. It also provides two 8-bit D/A converter channels (DA0, DA1), an integrated temperature sensor, and dedicated analog supply pins (AVCC0/AVSS0/VREFH0/VREFL0) - all confirmed in the R5F51111AGNE#2A's specification tables and pin function definitions.
Which package type does the R5F51111AGNE#2A use, and what are its key mechanical dimensions?
The R5F51111AGNE#2A uses the PWQN0048KB-A package: a 48-pin HWQFN with 7 × 7 mm body size, 0.5 mm pin pitch, and exposed thermal pad. This package is explicitly listed in Table 1.3 of the R01DS0190EJ0130 datasheet for the R5F51111AGNE orderable part number and supports all R5F51111AGNE#2A's I/O and peripheral functions per Table 1.2.
How does the R5F51111AGNE#2A handle low-power operation in battery-powered applications?
The R5F51111AGNE#2A offers three low-power modes, including software standby mode drawing just 0.44 µA typical current with RTC active and full register retention. Wake-up occurs in 4.8 µs via RTC alarm or external interrupt - verified in Section 1.1 of R01DS0190EJ0130.
