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. Table 1. Recommended devices (for consumer) VDD: 2.0 V to 3.6 V; 40 to +85 C [1] Device Freq. [MHz] Type Part number Supply Temp. range voltage range LPC1311 LPC1313 LPC1342 LPC1343 2 SMD CSTCC2M00G56-R0 2.0 to 3.6 [1] 4 CSTCR4M00G55-R0 8 CSTCE8M00G55-R0 16 CSTCE16M0V53-R0 25 CSTCW25M0X51-R0 40 to +85 C These resonators have load capacitors included so external load capacitors are not necessary. Suffix indicates packaging style. SMD type[ -R0:Plastic tape package( = 180mm), -B0:Bulk] For the LPC parts with USB (LPC1343 and LPC1342), the following resonators are recommended. Table 2. Recommended devices (for consumer) VDD: 2.0 V to 3.6 V; 40 to +85 C [1] Device Freq. [MHz] Type Part number Supply Temp. range voltage range LPC1342 LPC1343 12 SMD CSTCE12M0GH5L**-R0 2.0 to 3.6 16 SMD CSTCE16M0VH3L**-R0 [1] 40 to +85 C These resonators have load capacitors included so external load capacitors are not necessary. “**” means temporary part number; formal part number will be applied after the frequency measurement process on actual board by Murata.
