Technical Context

This device implements a dedicated USB PD control stack on an RL78/G13-class core with CISC architecture, 3-stage pipeline, and 0.04167 µs min instruction cycle at 24 MHz. Its USB subsystem supports full-speed (12 Mbps) and low-speed (1.5 Mbps) operation with UVBUSEN/UVBUS/UOVRCUR monitoring and integrated USB voltage regulator.

The peripheral set includes dual CSI, single UART, dual simplified I²C, two full I²C channels, eight 16-bit timers, watchdog, 12-bit interval timer, and programmable clock/buzzer output - all synchronized to a high-accuracy ±1.0% on-chip oscillator (selectable 1–48 MHz) and PLL-derived clocks.

FAQ

What USB Power Delivery specifications does the R9A02G015020GNP#AC0 support?

The R9A02G015020GNP#AC0 supports USB Specification Revision 2.0 (full-speed 12 Mbps and low-speed 1.5 Mbps) and Battery Charging Specification Revision 1.2, enabling 2.1 A/1.0 A charging modes. It does not implement USB PD 3.0 or USB-C Alternate Mode negotiation - its role is strictly BC 1.2-compliant sink control with integrated USB PHY. The R9A02G015020GNP#AC0 uses dedicated UVBUSEN and UOVRCUR pins to manage external power switches and overcurrent protection.

How many I/O pins does the R9A02G015020GNP#AC0 have, and what types are supported?

The R9A02G015020GNP#AC0 provides 23 I/O pins in its 32-pin QFN package. These include 5× N-ch open-drain outputs rated for 6 V tolerance, 8× TTL-input-capable pins, and 10× standard CMOS I/O. All pins support configurable pull-up resistors, and specific pins (e.g., P50–P55, P60–P64) serve dual roles as I²C, CSI, UART, or timer interfaces. The R9A02G015020GNP#AC0 datasheet confirms this count in Section 1.6 for the "32-pin (with USB)" variant.

What power-saving modes are available on the R9A02G015020GNP#AC0, and what are their typical currents?

The R9A02G015020GNP#AC0 offers HALT mode (0.72 mA), STOP mode (0.26 µA), and SNOOZE mode - all verified at VDD = 3.3 V and TA = 25°C per Section 2.3.2 of the datasheet. STOP mode disables the high-speed on-chip oscillator and system clock while retaining RAM content and allowing wake-up via external interrupt or RTC alarm. The R9A02G015020GNP#AC0 achieves ultra-low standby by leveraging RL78's deep-sleep architecture and integrated regulator control.

Does the R9A02G015020GNP#AC0 include on-chip memory for firmware storage and runtime data?

Yes, the R9A02G015020GNP#AC0 integrates 128 KB of code flash memory (organized in 1 KB blocks with security lock), 2 KB of data flash memory rated for 1,000,000 write cycles, and 7 KB of on-chip RAM. The data flash supports background operation (BGO), allowing program execution from code flash while rewriting data flash - critical for field-upgradable PD policy tables. This memory configuration is explicitly listed in Section 1.1 and Table 1-1 of the R9A02G015 datasheet.

Can the R9A02G015020GNP#AC0 operate across industrial temperature ranges?

Yes, the R9A02G015020GNP#AC0 is rated for operating ambient temperature TA = −40 to +85°C, qualified for consumer applications per Section 2.0 of the datasheet. Its high-accuracy ±1.0% on-chip oscillator (−20 to +85°C) and robust voltage detector (6-level LVD) ensure reliable USB PD negotiation and fault response across this full range. The R9A02G015020GNP#AC0 meets these specs without derating, making it suitable for enclosed power adapters and outdoor-rated power banks.
