The 60 MHz clock rate on this ARM7TDMI core delivers enough throughput to handle UART data streams at common baud rates, SPI transactions with external ADCs or DACs, and moderate control loops. The 128 KB Flash and 64 KB RAM split provides adequate space for firmware with a modest data buffer — suitable for protocol conversion or sensor aggregation, but not for large image processing or heavy floating-point math.
The ARM7TDMI core runs at 60 MHz.
We source and quote this obsolete part to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
No official pin-compatible replacement is listed by NXP. The LPC2100 series includes other density variants, but any substitution requires a full footprint and software compatibility check.
