LPC2138 in NXP LPC Family
The LPC2138 series by NXP Semiconductors is a high-performance 16/32-bit microcontroller family based on the ARM7TDMI-S core. Designed for real-time embedded applications, these MCUs integrate a wide range of serial communications interfaces and large on-chip memories. They provide a cost-effective solution for legacy industrial and consumer systems that require a balance between peripheral richness and low power consumption, supported by a proven architecture that ensures reliable operation in diverse hardware environments.
Variants in This Sub-Family
Variants within the LPC2138 sub-family primarily differ by their silicon revisions, such as the /01 version which offers enhanced functionality over the original release. Differences often include refined power-down modes, improved ADC accuracy, and specific performance optimizations. Packaging is standardized on the 64-pin LQFP, though temperature ratings can vary between commercial and industrial grades to meet specific environmental requirements.
