Embedded-system designers work in a very dynamic world, and a wide range of products are dependent on their efforts. However, the average embedded-system designer is not so dynamic when it comes to selecting a microcontroller. He tends to remain loyal to a specific type. But for anyone who is considering switching to a modern ARM7 microcontroller, iSystem has put together an inexpensive ARM7 kit.
LPC2138 features
• ARM7TDMI-S microcontroller
• 60 MHz clock rate (using internal PLL)
• 512 kB flash program memory
• 32 kB RAM
• Two 8-channel, 10- bit ADCs (2.44 μs conversion time)
• Two 32-bit timers
• six PWM outputs
• two UARTs
• I2C, SPI and SSP interfaces
• 9 interrupt inputs
• 3.3-V supply voltage
• All I/O lines 5-volt tolerant
