ARM7-Based MCU With FPGA Interface to Multi-Layer AHB
Offers seamless migration to CAP7 customizable MCUs for ARM7-plus-FPGA designs
SAN JOSE, Calif. --, June 18, 2008 -- Atmel® Corporation (Nasdaq: ATML - News) today announced the AT91CAP7E, the industry's first ARM7(TM)-based MCU with a direct FPGA interface. The AT91CAP7E is a standard microcontroller with an FPGA interface that makes the FPGA look and work like it is on the internal bus of the MCU. It provides customers with a two-chip, no-NRE, FPGA-plus ARM7 solution and offers an engineering-free migration path to a lower cost, and a lower power customizable MCU.
The CAP7E includes a six-layer advanced high-speed bus (AHB), peripheral DMA controller and 160 Kbytes of on-chip SRAM. On chip peripherals include USB 2.0 full speed device, SPI master and slave, two USARTs, three 16-bit timer counters, an 8-channel/ 10-bit analog to digital converter, plus a full-functioned system controller including interrupt and power control and supervisory functions. The FPGA interface on the CAP7E provides the FPGA with direct access to the CAP7E's on-chip AHB and peripheral DMA controller. This architecture eliminates FPGA-induced bus contention, off-loads MCU-to-FPGA communications from the CPU, and frees up the external bus interface for external memory access.
Interfacing an ARM7-based MCU to an FPGA has traditionally been done through the external bus interface (EBI) or programmable I/O. Either arrangement requires that the CPU transfer data to and from the FPGA one word-at-a-time, basically stealing CPU cycles that should be conserved for processing and limiting access to external memory during FPGA operations.
The FPGA interface on Atmel's CAP7E provides the FPGA with two AHB masters, four AHB slaves, a special direct AHB slave interface to an external RAM through the FPGA, and a programmable ROM that remaps the external RAM to emulate and debug the ROM code. Fourteen advanced peripheral bus (APB) slaves, two full-duplex DMA channels and 32-bit programmable I/O may be hardware selected to share I/O. An on-chip priority interrupt controller provides up to 13 encoded interrupts and two additional un-encoded interrupts for DMA transfers.
Third-party Tools and IP. The same C-compilers, RTOS, ICEs and IDEs used with Atmel's AT91SAM ARM®-based MCUs can be used with CAP(TM). Atmel has an extensive portfolio of silicon-proven peripherals that are available free of charge to customers migrating to a customizable MCU.
Availability and Pricing. Atmel's AT91CAP7E is available now and is priced at US$9.50 in quantities of 10,000 units in a 225 BGA package.
About CAP7 Customizable MCUs
Atmel's CAP7 customizable MCU is an ARM7-based microcontroller with a metal-programmable (MP) block with 450K gates or the equivalent of 56K FPGA logic cells (LC). Any functionality that has been implemented in an FPGA may be migrated directly to a CAP7 device with no special EDA tools or customer-side engineering. Standard FPGA software tools are all that is necessary to implement functions such as LCD controllers, DSP algorithms (e.g. GPS correlators, FFTs, FIR filters), and proprietary customer IP. A CAP7 implementation delivers as much as 8X better performance, consumes 98% less static power, and costs about 30% less than the FPGA-plus-MCU implementation.
About Atmel
Atmel is a worldwide leader in the design and manufacture of microcontrollers, advanced logic, mixed-signal, nonvolatile memory and radio frequency (RF) components. Leveraging one of the industry's broadest intellectual property (IP) technology portfolios, Atmel is able to provide the electronics industry with complete system solutions focused on consumer, industrial, security, communications, computing and automotive markets.
