Packaging

Package type: 64-LQFP (Low-Profile Quad Flat Package)

Body size: 10 x 10 mm nominal

Pin count: 64 pins, 16 pins per side

Pin pitch: typically 0.5 mm (verify exact pitch in the datasheet)

Mounting: Surface-mount, leaded gull-wing terminations

Materials: Molded epoxy encapsulation, copper leadframe, matte tin (Pb-free) plating

Thermal characteristics: No exposed thermal pad; use PCB copper planes and good layout for heat spreading. Ambient operating -40°C to +85°C (TA). For detailed θJA/θJC values and power dissipation, refer to the datasheet.

Electrical properties in package: Supply 1.65V–3.6V, internal oscillator available, ADC 4x10-bit, multiple serial buses accessible via package pins. See pin assignment for CAN, UART, SPI/SSP, I2C, ADC inputs, crystal pins, reset, VDD/VSS.

Pin configuration: Standard 64-LQFP pinout for LPC21xx family; check the pin map for exact functions and alternate functions.

Moisture sensitivity: Typically MSL 3 for LQFP; confirm in the product’s handling guidelines.

Reflow: Pb-free reflow compatible up to 260°C peak (follow JEDEC profile)

Shipment form: Tray (current listing). Tape-and-reel may be available on request depending on suffix; confirm with Y-IC sales.

Lifecycle

Status: LPC21xx is a mature NXP family. Some variants are active and some have NRND or EOL notices depending on suffix and region. This specific part’s lifecycle can vary by lot and date code. Y-IC tracks manufacturer PCNs and can confirm latest status.

Availability: Current stock listed as 2542 pcs (subject to change). RoHS3 compliant.

- LPC2124FBD64 (ARM7, 64-LQFP, same family; feature set varies, often without CAN)

- LPC2138FBD64 / LPC2148FBD64 (ARM7, 64-LQFP, same generation; added features like USB on LPC2148; pin mapping differs)

- LPC2368 (ARM7 with CAN; higher integration; different package options like LQFP-100)

- LPC1768 / LPC1769 (Cortex-M3, modern alternative with CAN and richer peripherals; different package/pinout)

- For automotive CAN-focused designs: NXP S32K1xx (Cortex-M4F; modern platform; different package/pinout)

If you need a drop-in replacement with minimal redesign, stay within LPC21xx 64-LQFP variants and confirm exact pin compatibility in the datasheet.
