With 32 KB SRAM, the part can hold moderate data buffers and stack depth for protocol stacks like Modbus RTU or a lightweight TCP/IP offload. The Flash is factory-programmable; no OTP lock means the firmware can be revised during production programming. ## Obsolete — sourcing reality and what replaces it NXP has marked this part as obsolete. Available through surplus and independent-distribution channel. ## Mixed-signal I/O — ADC and DAC on one die Sixteen 10-bit ADC channels and a single 10-bit DAC eliminate the need for external converters in many sensor-front-end and control-output designs. The ADC can sample up to 16 analog inputs (temperature, pressure, current sense) while the DAC provides a single analog setpoint or trim voltage. The internal oscillator further reduces external component count, though an external crystal can be used for tighter timing accuracy.","metaTitle":"NXP LPC2138FHN64,557 ARM7 MCU, 60MHz, 512KB Flash, 32KB RAM","metaDescription":"NXP LPC2138FHN64,557 ARM7TDMI-S 16/32-bit MCU, 60MHz, 512KB Flash, 32KB RAM, 47 I/O, -40°C to 85°C.
