NXP has designated this part as NRND. Still available for existing production but not for new designs. We source to order against RFQ.
60 MHz core handles real-time control loops and protocol parsing. 64 KB RAM limits buffer-heavy applications.
The LPC2106FHN48/01,55 is NRND (Not Recommended for New Designs) — it is not yet fully discontinued, but NXP advises against using it in new projects. Existing production can continue, but a last-time-buy or alternative sourcing should be planned.
NXP has not published an official direct replacement order code for this specific variant. The LPC2100 series is a legacy ARM7 family; newer designs typically migrate to NXP's LPC1700 (Cortex-M3) or LPC4300 (Cortex-M4) series, but these require a board redesign due to different pinouts and packages.
This is an ARM7TDMI-S MCU with a 60 MHz core, 128 KB Flash, 64 KB SRAM, 32 I/Os, I²C/SPI/UART interfaces, internal oscillator, POR/PWM/WDT peripherals, operating from 1.65 V to 3.6 V over -40°C to 85°C in a 48-HVQFN package.
