The MIPS32® 4KEm™ core from MIPS® Technologies is a member of the MIPS32 4KE™ processor core Family. It is a
high-performance, low-power, 32-bit MIPS RISC core designed for custom system-on-silicon applications. The core is
designed for semiconductor manufacturing companies, ASIC developers, and system OEMs who want to rapidly integrate
their own custom logic and peripherals with a high-performance RISC processor. It is highly portable across processes, and
can be easily integrated into full system-on-silicon designs, allowing developers to focus their attention on end-user
products. The 4KEm core is ideally positioned to support new products for emerging segments of the digital consumer,
network, systems, and information management markets, enabling new tailored solutions for embedded applications.
The AT24C512 provides 524,288 bits of serial electrically erasable and programmable
read only memory (EEPROM) organized as 65,536 words of 8 bits each. The device鈥檚
cascadable feature allows up to four devices to share a common two-wire bus. The
device is optimized for use in many industrial and commercial applications where lowpower
and low-voltage operation are essential. The devices are available in spacesaving
8-pin PDIP, 8-lead EIAJ SOIC, 8-lead JEDEC SOIC, 8-lead TSSOP, 8-lead
Leadless Array (LAP), and 8-lead SAP packages. In addition, the entire Family is available
in 2.7V (2.7V to 5.5V) and 1.8V (1.8V to 3.6V) versions.
The driver supports both the 16F and 18F families. The trick is that the driver carefully emulates the hardware UART found in the PIC18F452 processor. This information has unfortunately misled some into thinking it does not work with the 16F Family. During devlopment the driver was tested on a real PIC16F84A (as opposed to software emulation). To make sure nothing has been broken, I have just recompiled the code using SourceBoost 6.0 and it compiled without error.
The objective is to set up SPI communication between VTI Technologies digital pressure sensor
component and an MCU of an application device ATMEGA16L. In this code example:
?The MCU is configured
?SCP1000-D01 is initialized and configured
?The high resolution measurement mode is activated
?Temperature and pressure information is read always when the DRDY pin is in high state
Please refer to the document "SCP1000 Product Family Specification 8260800" for further
information on SCP1000 register addressing and SPI communication. This document applies to the
SCP1000-D01.

Introduction
? ?
The ARM Cortex -A8 microprocessor is the first applications microprocessor in ARM!ˉs
new Cortex Family. With high performance and power efficiency, it targets a wide
variety of mobile and consumer applications including mobile phones, set-top boxes,
gaming consoles and automotive navigation/entertainment systems. The Cortex-A8
processor spans a range of performance points depending on the implementation,
delivering over to 2000 Dhrystone MIPS (DMIPS) of performance for demanding
consumer applications and consuming less than 300mW for low-power mobile devices.
This translates into a large increase in processing capability while staying with the
power levels of previous generations of mobile devices. Consumer applications will
benefit from the reduced heat dissipation and resulting lower packaging and integration
costs.
