نقد و بررسی : میکروکنترلر LPC1768FBD100

* ARM Cortex-M3 processor, running at frequencies of up to 100 MHz
(LPC1768/67/66/65/64/63) or of up to 120 MHz (LPC1769). A Memory Protection Unit
(MPU) supporting eight regions is included.
* ARM Cortex-M3 built-in Nested Vectored Interrupt Controller (NVIC).
* Up to 512 kB on-chip flash programming memory. Enhanced flash memory accelerator
enables high-speed 120 MHz operation with zero wait states.
* In-System Programming (ISP) and In-Application Programming (IAP) via on-chip
bootloader software.
* On-chip SRAM includes:
* ۳۲/۱۶ kB of SRAM on the CPU with local code/data bus for high-performance CPU
access.
* Two/one 16 kB SRAM blocks with separate access paths for higher throughput.
These SRAM blocks may be used for Ethernet, USB, and DMA memory, as well as
for general purpose CPU instruction and data storage.
* Eight channel General Purpose DMA controller (GPDMA) on the AHB multilayer
matrix that can be used with SSP, I2S-bus, UART, Analog-to-Digital and
Digital-to-Analog converter peripherals, timer match signals, and for
memory-to-memory transfers.
* Multilayer AHB matrix interconnect provides a separate bus for each AHB master.
AHB masters include the CPU, General Purpose DMA controller, Ethernet MAC, and
the USB interface. This interconnect provides communication with no arbitration
delays.
* Split APB bus allows high throughput with few stalls between the CPU and DMA.
* Serial interfaces:
* Ethernet MAC with RMII interface and dedicated DMA controller. (Not available on
all parts, see Table 2.)
* USB 2.0 full-speed device/Host/OTG controller with dedicated DMA controller and
on-chip PHY for device, Host, and OTG functions. (Not available on all parts, see
Table 2.)
* Four UARTs with fractional baud rate generation, internal FIFO, and DMA support.
One UART has modem control I/O and RS-485/EIA-485 support, and one UART
has IrDA support.
* CAN 2.0B controller with two channels. (Not available on all parts, see Table 2.)
* SPI controller with synchronous, serial, full duplex communication and
programmable data length.
* Two SSP controllers with FIFO and multi-protocol capabilities. The SSP interfaces
can be used with the GPDMA controller.
* Three enhanced I2C bus interfaces, one with an open-drain output supporting full
I2C specification and Fast mode plus with data rates of 1 Mbit/s, two with standard
port pins. Enhancements include multiple address recognition and monitor mode.
* I2S (Inter-IC Sound) interface for digital audio input or output, with fractional rate
control. The I2S-bus interface can be used with the GPDMA. The I2S-bus interface
supports 3-wire and 4-wire data transmit and receive as well as master clock
input/output. (Not available on all parts, see Table 2.)
* Other peripherals:
* ۷۰ (۱۰۰ pin package) General Purpose I/O (GPIO) pins with configurable
pull-up/down resistors. All GPIOs support a new, configurable open-drain operating
mode. The GPIO block is accessed through the AHB multilayer bus for fast access
and located in memory such that it supports Cortex-M3 bit banding and use by the
General Purpose DMA Controller.
* ۱۲-bit Analog-to-Digital Converter (ADC) with input multiplexing among eight pins,
conversion rates up to 200 kHz, and multiple result registers. The 12-bit ADC can
be used with the GPDMA controller.
* ۱۰-bit Digital-to-Analog Converter (DAC) with dedicated conversion timer and DMA
support. (Not available on all parts, see Table 2)
* Four general purpose timers/counters, with a total of eight capture inputs and ten
compare outputs. Each timer block has an external count input. Specific timer
events can be selected to generate DMA requests.
* One motor control PWM with support for three-phase motor control.
* Two/one 16 kB SRAM blocks with separate access paths for higher throughput.
These SRAM blocks may be used for Ethernet, USB, and DMA memory, as well as
for general purpose CPU instruction and data storage.
