LPC2148 in NXP LPC Family
The LPC2148 sub-family by NXP Semiconductors is a series of high-performance 16/32-bit microcontrollers based on the ARM7TDMI-S processor core. These devices are notable for their integration of a full-speed USB 2.0 device controller and dual 10-bit ADCs. Designed to bridge the gap between simple 8-bit controllers and high-end application processors, the LPC2148 offers a balanced architecture for real-time applications requiring significant on-chip memory and standard serial communications in a compact 64-pin package.
Variants in This Sub-Family
Variants within the LPC214x sub-family primarily differ in their integrated Flash memory capacity and SRAM allocation. While the LPC2148 represents the high-end configuration with 512 KB Flash, other variants like the LPC2141, LPC2142, and LPC2144 offer scaled-down memory footprints starting from 32 KB. Peripheral sets remain largely consistent across the sub-family, though specific analog input channel counts may vary based on the package and pin-multiplexing requirements.
