1.3 Specification

The LP-EM-CC2340R53 is designed using the CC2340R53 wireless MCU that has a 48MHz Arm Cortex-M0+ processor, 512kB of in-system programmable flash, 12kB of ROM for bootloader and drivers, and 64kB of ultra-low leakage SRAM with full RAM retention in standby mode. In addition, the LP-EM-CC2340R53 is a 2.4GHz RF transceiver compatible with Bluetooth 5.3 Low Energy and IEEE 802.15.4 PHY and MAC, contains an integrated balun, supports over-the-air upgrade (OTA), and has a Serial Wire Debug (SWD) interface.

The MCU consumption has a 2.6mA active mode running CoreMark®, at 53μA/MHz, consumes less than 710nA in standby mode, and 165nA shutdown mode with wake-up on a pin.

The Radio consumption is 5.3mA in RX mode, 5.1mA in TX mode at 0dBm, and less than 11.0mA in TX at +8dBm. In additional, the radio is capable of –102dBm sensitivity for Bluetooth Low Energy 125kbps, –96.5dBm sensitivity for Bluetooth Low Energy 1Mbps, and –98dBm sensitivity for IEEE 802.15.4 (2.4GHz)

The LP-EM-CC2340R53 has support for 2-pin SWD debugging and a 32kHz external XTAL for the lowest power consumption and accurate RTC timekeeping. Each feature uses 2 pins that can be re-used as GPIOs if desired, bringing the number of GPIOs to a maximum of 26. In addition, this LaunchPad can support:

  • 3 × 16-bit and 1× 24-bit general-purpose timers, quadrature decode mode support
  • 12-bit ADC, 1.2Msps with external reference, 267ksps with internal reference, up to 12 external ADC inputs
  • 1× low power comparator
  • 1× UART
  • 1× SPI
  • 1× I2C
  • Real-time clock (RTC)
  • Integrated temperature and battery monitor
  • Watchdog timer
