LPC2132FHN64,557

Microcontrollers Overview

The LPC2132FHN64,557 is a single-chip 16/32-bit microcontroller based on the ARM7TDMI-S CPU. It integrates 64 kB of embedded high-speed flash memory and 16 kB of on-chip static RAM. The device supports execution at a maximum clock rate of 60 MHz via a programmable on-chip PLL. Key peripherals include one 8-channel 10-bit ADC, a single 10-bit DAC, two UARTs with hardware flow control, two Fast I2C-bus interfaces, SPI/SSP, and multiple timers. It operates on a single 3.0 V to 3.6 V supply with 5 V tolerant I/O pads.

Microcontrollers Feature Summary

• Features fast GPIO ports enabling rapid pin toggling and immediate pin reading regardless of function.
• Includes dedicated result registers for ADC channels to reduce interrupt processing overhead.
• Provides enhanced UART capabilities with fractional baud rate generation, auto-bauding, and hardware handshake flow control.
• Supports In-System Programming and In-Application Programming via an on-chip bootloader.

Microcontrollers Applications

• Access control systems
• Point-of-sale terminals
• Communication gateways and protocol converters
• Industrial control systems
• Medical systems

Microcontrollers Procurement Notes

Verify the specific ordering suffix against NXP documentation to confirm package type and temperature range. Ensure compatibility with existing board layouts regarding the HVQFN64 footprint. Confirm that the component meets all required environmental standards for the intended deployment environment before finalizing procurement.

Microcontrollers Selection Notes

Select this model when 64 kB of flash and 16 kB of RAM are required alongside analog conversion capabilities. It is suitable for designs needing a compact HVQFN64 package. Consider the 60 MHz performance limit and 3.3 V operating voltage when defining system power and timing constraints.

Microcontrollers Part Context

This component belongs to the LPC213x family of microcontrollers, which share a common ARM7TDMI-S core architecture. Variants within the family differ primarily in flash memory size, SRAM capacity, and the number of available ADC channels. The LPC2132 specifically offers a mid-range configuration balancing memory resources with peripheral integration.

Microcontrollers Replacement Considerations

LPC2132FBD64/01 is a form, fit, and function compatible alternative featuring an LQFP64 package instead of HVQFN64. Other family members like LPC2131 or LPC2134 may serve as substitutes if memory or peripheral requirements differ.
