2. Device Description
2.1 Technical Specifications
2.1.1 Operating Parameters
2.1.2 Power
The Skywire RL78/Kurumi Adapter requires 5V and 3.3V inputs. Connector J1
accepts 5V input voltage and is used to supply power to the Skywire 4V Power
Supply. The acceptable input Voltage range for J1 is 4.8-5.2V. Do not exceed
5.5V.
The Skywire Cellular Modem will regularly consume high amounts of current
(~750 mA) from the adapters power supply. It is recommended to have 1A of
available source current available for the adapter board.

3. Operating Modes
3.1 RL78/G13 Demonstration Kit PMOD Adapter
3.1.1 About
The PMOD interface on the Skywire RL78-Kurumi Adapter adheres to the Digilent
PMOD specifications for Type 2A (Expanded SPI) PMOD Interface with a standard
twelve-pin connector.
The PMOD interface connects to the Renesas Demonstration Kit for the
RL78/G13 (YRDKRL78G13) through the PMOD2 connector. The adapter’s
onboard SPI to UART converter provides protocol translation allowing for the
demonstrations kits Type 2A (Expanded SPI) PMOD Interface to communicate
with the Skywire module.

3.1.3 Switch configuration
SW1 is used to control the configuration mode of the adapter. To configure the
adapter for use with the PMOD connection do the following:
1. Remove power from J1 and the PMOD connection.
2. Place SW1.1-SW1.5 in the on position.
3. Place SW1.6 in the off position.
4. Configuration complete.
3.1.4 Connections
The Skywire RL78-Kurumi Adapter connects to the RL78/G13 through a Type 2A

3.1.5 SPI to UART Chip Configuration
To configure the XR20M1170 SPI to UART interface for communication between
the PMOD interface (SPI) and the Skywire Cellular Modem (UART, 115200 bps)
use the configuration sequence in the table below. The SPI interface from the
host processor should be configured to SPI MODE0, most Significant bit first, and
the clocking rate must be 16 MHz or lower.
