NXP | LPC2102FBD48,151

The LPC2101/02/03 microcontrollers are based on a 16-bit/32-bit ARM7TDMI-S CPU with real-time emulation that combines the microcontroller with 8 kB, 16 kB or 32 kB of embedded high-speed flash memory. A 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at the maximum clock rate. For critical performance in interrupt service routines and DSP algorithms, this increases performance up to 30 % over Thumb mode. For critical code size applications, the alternative 16-bit Thumb mode reduces code by more than 30 % with minimal performance penalty.

Enhanced features are available in parts LPC2101/02/03 labelled Revision A and higher :

• Deep power-down mode with option to retain SRAM memory and/or RTC.
• Three levels of flash Code Read Protection (CRP) implemented.

Key features :

• 16-bit/32-bit ARM7TDMI-S microcontroller in tiny LQFP48 and HVQFN48 packages.
• 2 kB/4 kB/8 kB of on-chip static RAM and 8 kB/16 kB/32 kB of on-chip flash program memory. 128-bit wide interface/accelerator enables high-speed 70 MHz operation.
• ISP/IAP via on-chip bootloader software. Single flash sector or full chip erase in 100 ms and programming of 256 bytes in 1 ms. 
• EmbeddedICE-RT offers real-time debugging with the on-chip RealMonitor software.
• The 10-bit ADC provides eight analog inputs, with conversion times as low as 2.44 ms per channel and dedicated result registers to minimize interrupt overhead.
• Two 32-bit timers/external event counters with combined seven capture and seven compare channels.
• Two 16-bit timers/external event counters with combined three capture and seven compare channels.
• Low power Real-Time Clock (RTC) with independent power and dedicated 32 kHz clock input.
• Multiple serial interfaces including two UARTs (16C550), two Fast I2C-buses (400 kbit/s), SPI and SSP with buffering and variable data length capabilities.
• Vectored interrupt controller with configurable priorities and vector addresses.
• Up to thirty-two, 5 V tolerant fast general purpose I/O pins.
• Up to 13 edge or level sensitive external interrupt pins available.
• 70 MHz maximum CPU clock available from programmable on-chip PLL with a possible input frequency of 10 MHz to 25 MHz and a settling time of 100 ms.
• On-chip integrated oscillator operates with an external crystal in the range from 1 MHz to 25 MHz.
• Power saving modes include Idle mode, Power-down mode with RTC active, and Power-down mode.
• Individual enable/disable of peripheral functions as well as peripheral clock scaling for additional power optimization.
• Processor wake-up from Power-down and Deep power-down (Revision A and higher) mode via external interrupt or RTC.
