LPC2132FBD64/01151 概述
Key specifications include a 60 MHz maximum CPU clock from the on-chip PLL, 128-bit wide memory interface with a unique accelerator enabling 32-bit code execution at maximum clock rate, single 3.3 V power supply operation, and on-chip integrated oscillator. The MCU targets embedded control, industrial networking, and USB device applications where deterministic real-time behavior is required.
The LPC2132 belongs to the LPC2131/32/34/36/38 family which scales flash memory from 32 KB to 512 KB. Its 64 KB flash and 16 KB SRAM position it as a mid-density member of the family, suitable for applications requiring modest program and data memory plus USB connectivity. The peripheral mix (USB, ADC, DAC, RTC, multiple timers) provides a complete system-on-chip solution for industrial, medical, and consumer products.
Typical applications include industrial control and automation, USB peripherals and bridges, point-of-sale terminals, medical instrumentation, smart card readers, and general embedded control. The on-chip USB 2.0 full-speed device controller simplifies USB device designs by eliminating external PHY and reducing BOM cost.
When designing with this device, ensure the JTAG and Embedded Trace Macrocell (ETM) debug access is preserved for development and field updates; the ARM7TDMI-S supports both real-time emulation and embedded trace. ISP/IAP flash programming via UART enables in-system firmware updates without removing the part from board-level access.

典型应用
LPC2132FBD64/01151 适用于 6 应用s: Industrial Control and Automation, USB Peripherals and Bridges, Point-of-Sale Terminals, Medical Instrumentation, Smart Card Readers, General Embedded Control.
Industrial Control and Automation
The LPC2132FBD64/01151 fits industrial control applications requiring deterministic real-time execution. Its 60 MHz ARM7TDMI-S core with 128-bit memory interface delivers 32-bit code execution at peak throughput, ideal for PLC modules, motor controllers, and HMI front-ends. The 10-bit ADC samples analog sensor inputs (temperature, pressure, position) at rates sufficient for industrial loop control. Two UARTs support RS-232/422/485 communication with industrial sensors and motor drives via external transceivers, while the SPI and I2C interfaces connect to digital sensors, EEPROMs, and display drivers. The -40C to +85C industrial temperature range and 3.3 V single-supply design simplify integration into factory floor equipment with standard 24V-to-3.3V DC-DC rails.
推荐
USB Peripherals and Bridges
The LPC2132FBD64/01151 integrates a USB 2.0 full-speed (12 Mbps) device controller with on-chip PHY and dedicated PLL, eliminating the external transceiver and crystal typically required for USB implementations. This makes the part ideal for USB-to-serial bridges, USB HID devices (keyboards, mice, game controllers), USB mass-storage devices, and USB vendor-class peripherals. The 64 KB flash accommodates USB class drivers plus application logic, while 16 KB SRAM handles USB endpoint buffers and protocol stacks. Multiple UARTs enable USB-to-UART bridge products, and the I2C/SPI ports support USB-to-I2C/SPI bridges for legacy equipment connectivity.
推荐
Point-of-Sale Terminals
Point-of-sale (POS) terminals benefit from the LPC2132FBD64/01151's integrated USB device controller (for PC connectivity), 10-bit ADC (for battery voltage monitoring and analog sensor inputs), 10-bit DAC (for audio feedback tones), and RTC with battery backup domain (for transaction timestamping). The 64 KB flash stores payment terminal firmware, encryption libraries, and display drivers, while 16 KB SRAM handles transaction buffers and display frame buffers. Two UARTs support magnetic stripe readers and external peripherals. The compact 64-LQFP package fits handheld POS form factors, and the 60 MHz ARM7 core executes cryptographic operations (AES, DES) fast enough for sub-second payment authorization cycles.
推荐
Medical Instrumentation
Medical instrumentation such as portable patient monitors, diagnostic instruments, and home-care devices leverage the LPC2132FBD64/01151's low-power 3.3 V operation, integrated USB for data transfer to PCs/hospital networks, 10-bit ADC for vital-sign sensors (SpO2, temperature, ECG), and RTC for time-stamped measurement records. The ARM7TDMI-S deterministic real-time execution supports critical measurement loops and safety interrupt routines. The 64 KB flash and 16 KB SRAM accommodate device firmware plus measurement algorithm libraries. The -40C to +85C operating range suits clinical environments, and the LQFP-64 package is compatible with standard medical-grade PCB manufacturing processes.
推荐
Smart Card Readers
Smart card readers benefit from the LPC2132FBD64/01151's USB device controller (for PC host connectivity), multiple UARTs (for contact smart card interfaces via external UART-to-ISO7816 bridges), I2C/SPI ports (for contactless/NFC front-ends), and RTC (for transaction logging). The 64 KB flash stores smart card reader firmware with multiple card protocol stacks (T=0, T=1), while 16 KB SRAM handles cryptographic operations and protocol buffers. The integrated peripherals reduce BOM cost for compact USB smart card readers used in banking, identification, and access control applications.
推荐
General Embedded Control
General embedded control applications (printers, scanners, appliance controllers, HVAC interfaces, building automation) leverage the LPC2132FBD64/01151's balance of flash (64 KB), SRAM (16 KB), peripherals, and connectivity. The dual UARTs support Modbus or DMX512 industrial protocols, while SPI and I2C connect to sensors, motor drivers, and display modules. The 10-bit DAC generates analog control signals for lighting dimmers or motor speed control, and the 10-bit ADC reads analog feedback signals. The RTC with battery backup enables scheduled operation and time-stamped event logging, ideal for HVAC thermostats and access control panels.

设计说明
The LPC2132FBD64/01151 requires a stable 3.3 V supply within 3.0-3.6 V tolerance. Place 100 nF decoupling capacitors close to each VDD/VSS pin pair, plus a bulk 10 uF tantalum or ceramic capacitor at the supply input. The analog supply (VDDA) and digital supply (VDD) should be tied to the same 3.3 V rail but filtered separately - place a ferrite bead between VDD and VDDA and decouple VDDA with 100 nF + 10 nF caps near the pin. The RTC domain (VBAT) requires its own decoupling if a backup battery is used.
Route the JTAG signals (TCK, TMS, TDI, TDO, TRST) away from high-speed switching signals and keep trace lengths under 50 mm to ensure reliable debug access. The Embedded Trace Macrocell (ETM) port adds 4-12 additional output pins for instruction tracing - allocate board space for the Mictor/TRACE connector if real-time trace is required during development. The USB DP/DM traces must be 90-ohm differential and matched within 2 mm of length; route them on the top layer only with a continuous ground plane beneath.
Do not exceed 60 MHz CPU clock - the on-chip PLL multiplies the 1-25 MHz external crystal by an integer ratio and over-clocking causes flash memory access failures. The crystal oscillator requires an external load capacitor matching the crystal's CL specification (typically 10-33 pF) - incorrect values cause startup failures or frequency error. When using ISP programming via UART0, ensure the bootloader entry sequence (ISP pin high on reset) is accessible in production hardware for field firmware updates.
