1. Overview

RIGEL REV C is an ESP32-based customized module developed by Espressif for Whirlpool.

•

W11261889, which features two PCB antennas plus one IPEX/U.FL antenna.

RIGEL REV C features an 16 MB external ﬂash. The ordering information of RIGEL REV C is listed in Table 1-1.

Table 1-1. Ordering Information of RIGEL REV C

Part number Embedded chip Flash Antenna

W11261889 ESP32-D0WD 16 MB 2 × PCB antennas, 1 × IPEX/U.FL antenna

At the core of the module is ESP32-D0WD chip, one of the SoCs among the ESP32 series. The chip contains two low-power Xtensa® 32-bit LX6 microprocessors that can be individually controlled, and the CPU clock frequency is adjustable from 80 MHz to 240

MHz. The user may also power off the CPU and make use of the low-power co-processor to constantly monitor the peripherals for changes or crossing of thresholds. The chip integrates a rich set of peripherals, ranging from capacitive touch sensors, Hall sensors, SD

card interface, Ethernet, high-speed SPI, UART, I

S and I2C.

ESP32-D0WD's internal memory includes:

448 KB of ROM for booting and core functions.

•

520 KB of on-chip SRAM for data and instructions.

• 8 KB of SRAM in RTC, which is called RTC FAST Memory and can be used for data

storage; it is accessed by the main CPU during RTC Boot from the Deep-sleep mode.

8 KB of SRAM in R

•

the co-pr

1 Kbit of eFuse: 256 bits are used for the system (MAC address and chip

•

ocessor during the Deep-sleep mode.

TC, which is called R

TC SLOW Memory and can be accessed by

conﬁguration) and the remaining 768 bits are reserved for customer applications, including ﬂash-encryption and Chip-ID.

📖 Note:

For more information on ESP32, please refer to ESP32 Datasheet.

3. Peripherals and Interfaces

3.1. Radio/SOC & Class B Micro

UART should be used to interface between the Radio/SOC and the class B micro. The Radio/SOC provides a wake-up input line (GPI39_WKUP_IN) and an interrupt output line (GPIO15_WKUP_OUT_MTDO) to the class B micro.

3.2. Radio/SOC & WIN Bus

The Radio/SOC provides UART communication (GPIO27_WIN_TX/GPI37_WIN_RX) to the WIN bus for optional use. Flow control is not required.

3.3. Interface—Display

The Radio/SOC provides eight signal lines (a 4-line SPI and 4 GPIOs) to display:

• Display reset

• SPI data out from display

•

SPI SS

• SPI CLK

• SPI data in to display

•

Display CD

• Display TE

• Display control for back-light driver

3.4. Interface—JATG

The Radio/SOC provides a JTAG interface for debugging. However, this interface should only be used during the development.

3.5. Interface—Programming

The Radio/SOC provides a standalone programming interface, which includes

UART0_RX, UART0_TX, GPIO0_I2S_CLK/Boot, EN, VDD and GND.
