About the Musca-B1 test chip and board
The Musca
‑
B1 board is a development system that demonstrates the foundation of single-chip secure
Internet of Things
(IoT) endpoints.
Purposes of the Musca-B1 test chip and board
The Arm Musca
‑
B1 board provides access to the Arm Musca
‑
B1 test chip that implements the Arm
CoreLink SSE
‑
200 Subsystem for Embedded product.
Major components and systems
The system enables development and evaluation of custom software on the Musca
‑
B1 test chip. The
board and Musca
‑
B1 test chip provide the following main features:
• Musca
‑
B1 test chip that includes, but is not limited to, the following:
— CoreLink SSE
‑
200 subsystem that contains two Arm Cortex
‑
M33 processors.
— Peripheral and Arduino Expansion Shield interfaces.
• On-board DAPLink that provides the following access:
—
Serial Wire Debug
(SWD).
—
USB Mass Storage Device
(USBMSD) for uploading new firmware.
— USB serial port. The UART on the Musca
‑
B1 test chip does not support hardware flow control.
— Remote reset.
• On-board:
— 3-axis orientation and motion sensor (gyro sensor).
— Temperature sensor/ADC/DAC.
—
Quad Serial Peripheral Interface
(QSPI) 8MB boot flash.
—
Secure Digital I/O
(SDIO) microSD card.
• P-JTAG processor debug and SWD header.
• User RGB LED, status LEDs, user reset, and ON/OFF push buttons.
• The board is powered from USB 5V power or Li-ion rechargeable battery backup, battery not
supplied, selectable by a slider switch.
• Headers for Arduino Expansion Shield to support development of custom designs:
— 16 3V3 GPIO.
— UART. No hardware flow control.
— SPI, master only.
— I
2
C, master only.
— I
2
S three-channel, master only.
— 3-channel
Pulse Width Modulation
(PWM).
— 6-channel analog interface from the on-board combined ADC, DAC, and GPIO.
