Product details

The LPC2132FHN64,557: Rated for -40°C to 85°C ambient, this MCU handles factory-floor heat and outdoor telecom cabinet swings without derating the core clock. The 64-HVQFN (9x9 mm) exposed-pad package pulls heat into the ground plane — mount it with a thermal via array under the pad if the design pushes the I/O bank near the 47-line limit.

Peripherals and data converters

The 8-channel 10-bit ADC and single 10-bit DAC cover analog front-end tasks like current-sense feedback or set-point generation.

Frequently asked questions

What is the direct replacement for LPC2132FHN64?

The LPC2132FHN64/01 is the pin-compatible replacement from NXP. It shares the same footprint, memory, and peripheral set, with an updated bootloader.

What is LPC2132FHN64,557's listed speed?

The core runs at 60 MHz, which is the maximum clock for the ARM7TDMI-S core in this device.
