Product details

180 MHz Cortex-M3 with 512 KB Flash — what it means for the BOM

The NXP LPC1812JBD144E is a 32-bit ARM Cortex-M3 MCU clocked at 180 MHz, with 512 KB of on-chip Flash, 104 KB of SRAM, and 16 KB of EEPROM.

Industrial temperature grade and package

Rated for -40°C to 105°C ambient, the LPC1812JBD144E fits into engine-bay electronics, outdoor telecom cabinets, and motor-drive enclosures without forced air. The 144-LQFP package is a standard footprint for mid-complexity MCU boards; the 83 general-purpose I/O lines leave plenty of margin for parallel buses, keypad matrices, and status LEDs alongside the primary control interface.

Frequently asked questions

What is the closest pin-compatible alternative to LPC1812JBD144E in this family?

Within the LPC18xx series, the LPC1812JBD144E is a specific density variant (512 KB Flash, 104 KB RAM, 16 KB EEPROM). Pin-compatible siblings with different Flash/RAM densities exist across the LPC18xx value line, but the exact memory mix and peripheral set differ — verify the target part's data sheet for full compatibility before substituting.

What is LPC1812JBD144E's listed speed?

The LPC1812JBD144E runs at 180 MHz, which is the maximum core clock for this ARM Cortex-M3 device.
