Driving the LPC1300 with Murata resonators
1. Introduction
The LPC1300 series microcontrollers are based on the ARM Cortex-M3 core operating at
up to 72 MHz. These low power 32-bit microcontrollers feature serial interfaces including
USB, UART, and I2C. The controllers are ideal for applications such as eMetering,
medical, POS, and industrial networking.
The LPC1300 devices have an integrated IRC oscillator. On the LPC1300, the IRC is
nominally 12 MHz and accurate within 1 % over temperature and voltage. Many
applications can utilize the IRC as the clock source; others may use a suitable crystal for
more accuracy, particularly for USB applications. The LPC1300 device can also use a
resonator as a clock source.
2. Characterization results
Based on characterization results, the following tables detail the most suitable devices
available from Murata. Note that devices from other manufacturers can also be used.
