LPC2148

(Reference - LPC2148 User Manual )

The LPC2148 microcontroller is designed by Philips (NXP Semiconductor) with several in-built features & peripherals. Due to these reasons, it will make more reliable as well as the efficient option for Embedded system Designers. LPC2148 is a 32-bit microcontroller based on ARM7 family.

Features of LPC2148 :

• The LPC2148 is a 64 pin microcontroller and available in a small LQFP64 package (Low-profile Quad Flat Package).

• ISP (in system programming) or IAP (in application programming) using on-chip boot loader software.

• On-chip RAM = 40 kB

• On-chip flash memory is 512 kB

• Speed = 60 MHz Max.

• USB 2.0 full speed device controller

• Two 10-bit ADCs = 14 analogs i/ps

• One 10 bit DAC with analog o/p.

• Two 32 bit timers-2, PWM unit.

• 1 watchdog Timer

• 1 RTC (real time clock)

• Two UARTs, two I2C-buses, two SPI-buses

• 5 volts tolerant quick general purpose Input/output pins in a small LQFP64 package.

• Outside interrupt pins-21.

• 60 MHz of utmost CPU CLK-clock obtainable from the programmable-on-chip phase locked loop by resolving time is 100 μs.

• Onchip oscillator owill work by an external crystal that ranges from 1 MHz-25 MHz

• The modes for power-conserving mainly comprise idle & power down.
