LPC2148 3D Model

The LPC2148 microcontroller is based on a 16-bit/32-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, that combine the microcontroller with embedded high-speed flash memory ranging from 32 kB to 512 kB. A 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at the maximum clock rate. For critical code size applications, the alternative 16-bit Thumb mode reduces code by more than 30 % with a minimal performance penalty.

• It is 16 or 32 bit ARM 7 family-based microcontrollers and is available on the market in small packages such as LQFP64.

• Its programming time is 1 millisecond for 256 bytes and 400 milliseconds for erasing the full chip data.

• It is used on-chip bootloader software during the ISP (in-system programming) and IAP ( in application programming)

• It has 8 kB to 40 KB on-chip static RAM and 32 kB to 512 kB on-chip flash memory.

• It offers a high-speed operation at a frequency of 60 MHz with a wide range of interfaces almost 128 bits.

• It has an embedded ICE RT and embedded trace interface which offers the tracing of instruction execution with high speed with real-time debugging.

• It offers a changeable output with a 10 bit DAC( digital to analogue converter).

• This LQFP64 small package also has 5 volts input-output pins for any general purposes.

• For counting the external events it has two 32 bit timers, a watchdog timer and a PWM unit.

• LPC2148 offers the changeable input with 10 bit ADC (analogue to digital converter) with very conversion time such as 2.44μs / channel.

• The modes, which are used for power conversion are called idle and power down.

• It has several serial interfaces such as two 12C buses, two 16C550 UARTs with 400 Kbit speed.

• It has a 1 MHz to 25 MHz on-chip incorporated oscillator which works as an exterior crystal.

• It also has individual enable or disable peripheral function and peripheral SLK scaling for extra power optimization.
