The LPC4076 is an ARM Cortex-M4 based digital signal controller for embedded applications requiring a high level of integration and low power dissipation. The ARM Cortex-M4 is a next generation core that offers system enhancements such as low power consumption, enhanced debug features, and a high level of support block integration. The ARM Cortex-M4 CPU incorporates a 3-stage pipeline, uses a Harvard architecture with separate local instruction and data buses as well as a third bus for peripherals, and includes an internal prefetch unit that supports speculative branching. The ARM Cortex-M4 supports single-cycle digital signal processing and SIMD instructions. A hardware floating-point processor is integrated in the core for several versions of the part. The LPC408x/7x adds a specialized flash memory accelerator to accomplish optimal performance when executing code from flash. The LPC408x/7x is targeted to operate at up to 120 MHz CPU frequency.
- Functional replacement for LPC23xx/24xx and LPC178x/7x family devices.
- ARM Cortex-M4 core:
- ARM Cortex-M4 processor, running at frequencies of up to 120 MHz.
- ARM Cortex-M4 built-in Memory Protection Unit (MPU) supporting eight regions.
- ARM Cortex-M4 built-in Nested Vectored Interrupt Controller (NVIC).
- Hardware floating-point unit (not all versions).
- Non-maskable Interrupt (NMI) input.
- JTAG and Serial Wire Debug (SWD), serial trace, eight breakpoints, and four watch points.
- System tick timer.
- Memory:
- 512 kB on-chip flash program memory with In-System Programming (ISP) and In-Application Programming (IAP) capabilities. The combination of an enhanced flash memory accelerator and location of the flash memory on the CPU local code/data bus provides high code performance from flash.
- Up to 96 kB on-chip SRAM includes: 64 kB of main SRAM on the CPU with local code/data bus for high-performance CPU access.Two 16 kB peripheral SRAM blocks with separate access paths for higher throughput. These SRAM blocks may be used for DMA memory as well as for general purpose instruction and data storage.
- Up to 4032 byte on-chip EEPROM
