LPC2388FBD144 - Brand New NXP Semiconductors Microcontrollers
-
Description
The LPC2388FBD144 is a microcontroller belonging to the Microcontrollers category. It is powered by a 16-bit/32-bit ARM7TDMI-S CPU with real-time emulation. It comes with 512 kB of embedded high-speed flash memory. The memory interface is 128-bit wide and it has a unique accelerator architecture, which enables 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. Additionally, it has 16-bit Thumb mode that reduces code by more than 30% with minimal performance penalty, making it suitable for critical code size applications.
Specifications and features
- ARM7TDMI-S processor, running at up to 72 MHz
- Up to 512 kB on-chip flash program memory with In-System Programming (ISP) and In-Application Programming (IAP) capabilities
- 64 kB of SRAM on the ARM local bus for high performance CPU access
- 16 kB SRAM for Ethernet interface which can also be used as general-purpose SRAM
- 16 kB SRAM for general-purpose DMA use, also accessible by the USB
- Dual Advanced High-performance Bus (AHB) system that provides for simultaneous Ethernet DMA, USB DMA, and program execution from on-chip flash with no contention between those functions. A bus bridge allows the Ethernet DMA to access the other AHB subsystem
- EMC provides support for static devices such as flash and SRAM as well as off-chip memory mapped peripherals
- Advanced Vectored Interrupt Controller (VIC), supporting up to 32 vectored interrupts
- General Purpose DMA controller (GPDMA) on AHB that can be used with the SSP serial interfaces, the I2S-bus port, and the Secure Digital/MultiMediaCard (SD/MMC) card port, as well as for memory-to-memory transfers
- Serial Interfaces:
- Ethernet MAC with associated DMA controller. These functions reside on an independent AHB
- USB 2.0 device/host/OTG with on-chip PHY and associated DMA controller
- Four UARTs with fractional baud rate generation, one with modem control I/O, one with IrDA support, all with FIFO
- CAN controller with two channels
- SPI controller
- Two SSP controllers, with FIFO and multi-protocol capabilities. One is an alternate for the SPI port, sharing its interrupt and pins. These can be used with the GPDMA controller
- Three I2C-bus interfaces (one with open-drain and two with standard port pins)
- I2S (Inter-IC Sound) interface for digital audio input or output. It can be used with the GPDMA
Application Scenarios
The LPC2388FBD144 can be used in various applications such as industrial control, medical systems, protocol converters, and communications.
