LPC54101J256UK49Z

The LPC5410x are ARM Cortex-M4 based microcontrollers for embedded applications. These devices include an optional ARM Cortex-M0+ coprocessor, 104 kB of on-chip SRAM, up to 512 kB on-chip flash, five general-purpose timers, one State-Configurable Timer with PWM capabilities (SCTimer/PWM), one RTC/alarm timer, one 24-bit Multi-Rate Timer (MRT), a Repetitive Interrupt Timer (RIT), a Windowed Watchdog Timer (WWDT), four USARTs, two SPIs, three Fast-mode plus I2C-bus interfaces with high-speed slave mode, and one 12-bit 5.0 Msamples/sec ADC. The ARM Cortex-M4 is a 32-bit core that offers system enhancements such as low power consumption, enhanced debug features, and a high level of support block integration. The ARM Cortex-M4 CPU incorporates a 3-stage pipeline, uses a Harvard architecture with separate local instruction and data buses as well as a third bus for peripherals, and includes an internal prefetch unit that supports speculative branching. The ARM Cortex-M4 supports single-cycle digital signal processing and SIMD instructions. A hardware floating-point unit is integrated in the core.

• Dual processor cores: ARM Cortex-M4 and ARM Cortex-M0+.
• Analog peripheral: 12-bit, 12-channel, Analog-to-Digital Converter (ADC) supporting 5.0 Msamples/s. The ADC supports two independent conversion sequences.

  • 12 MHz internal RC oscillator.
  • External clock input for clock frequencies of up to 25 MHz.
  • Internal low-power, watchdog oscillator (WDOSC) with a nominal frequency of 500 kHz.
  • 32 kHz low-power RTC oscillator.
• Power-saving modes and wake-up
• Single power supply 1.62 V to 3.6 V.
• Power-On Reset (POR).
• Brown-Out Detect (BOD) with separate thresholds for interrupt and forced reset.
• JTAG boundary scan supported.
• Unique device serial number (128 bit) for identification.
• Operating temperature range -40 °C to 105 °C.
• Available in a 3.288 x 3.288 x 0.54 mm WLCSP49 package.
