PIN and Block DIAGRAM

The device contains a total of 100 pins that contain different features. Although, pin connect block allows the selected pins to perform more than one function. Configuration registers command the multiplexers to allow connection between the pin and the on-chip peripherals. Most pins can also be configured as open-drain outputs or to have a pull-up, pull-down, or no resistor enabled.

What is LPC1768FBD100,551？

LPC1768FBD100,551 is a 32-bit microcontroller with cost-effective Cortex-M3 core based on Ethernet, USB, CAN and 12-bit ADC and speeds up to 120MHz. It can make a CPU more flexible, adaptable and fast due to its characteristics. The maximum clock speed of the microcontroller is 100MHz and operates at temperature range of -40 °C to 85 °C.

The device has 512KB of flash memory size and 64KB of SRAM size. It has a feature of multi-layer AHB bus that offers high-bandwidth peripherals like USB and Ethernet to operate continuously with harming performance. LPC1768FBD100,551 comes in LQFP100 package.

It is pin-compatible to the 100-pin LPC236x Arm7-based microcontroller series. The Arm Cortex-M3 offers many new features, including a Thumb-2 instruction set, low interrupt latency, hardware divide, interruptible/continuable multiple loads and store instructions, the automatic state saves and restore for interrupts, tightly integrated interrupt controller with wake-up interrupt controller, and multiple core buses capable of simultaneous accesses.
