Flash ISP single Core
The
Atmel® AT89LP family takes 8051 microcontroller power to a new
level. These high performance 8-bit microcontrollers execute most instructions
in a single clock cycle, compared to 12 clock cycles in the classic 8051 CPU.
At the same MIPS throughput as the classic 8051, existing applications can use
a much lower clock frequency, enabling power consumption reduction by up to 80
percent. Application performance can be boosted up to 20 MIPS throughput 12
times faster than the traditional 8051 core.
For
example AT89LP214, AT89LP215, AT89LP216 etc, etc.
Flash ISP (In system Programmable)
Atmel
offers a variety of high performance Flash 8051 microcontrollers featuring
in-system programming (ISP). Their integrated Flash memory can be programmed
either in parallel mode or in serial mode with the appropriate parallel/ISP
software, respectively.
They
feature a wide range of internal RAM configurations, plus rich features such as
interrupt controllers and timer/counters. Select models feature an A/D
converter, Boot Flash memory, and Programmable Counter Arrays. Their highly
efficient design can help reduce system power consumption by bringing the clock
frequency down to any value — even DC — without loss of data.
Software-selectable
modes of reduced activity and an 8 bit clock prescaler can further control
power consumption.
The
rich functionality and efficiency of Atmel 8051 Flash ISP microcontrollers make
them ideal for applications that need A/D conversion, pulse width modulation,
high speed I/O and counting capabilities such as industrial control, consumer
goods, alarms, motor control, and more.
For
example AT89C5115, AT89LS , AT89S series.
Flash Reprogrammable
Atmel
offers several 8051 reprogrammable Flash microcontrollers that can support a
variety of embedded applications. For example, the AT89C4051 is a low-voltage,
high-performance CMOS 8-bit microcontroller with 4K bytes of Flash programmable
and erasable read-only memory. The device is manufactured using Atmel's
high-density nonvolatile memory technology and is compatible with the
industry-standard MCS-51 instruction set.
For
Example AT89C2051, AT89C5051 etc.
CAN Networking MCU'S
Introduced
in 1986, Controller Area Network (CAN) technology was originally intended for
automotive engine control communication. It has rapidly gained popularity to
support a wide range of growing applications, including medical devices,
avionics, factory and industrial automation, and maritime environments.
Atmel
is well positioned to support CAN networking with a broad portfolio of 8051
microcontroller flash technology, together with extensive experience in CAN
networking.
For
example, the AT89C51CC01, AT89C51CC02, AT89C51CC03 deliver 5 MIPS at 5V, and
16KBytes to 64KBytes Flash. They can support a wide range of slave applications
such as proximity sensor, DeviceNet I/O, textile machine I/O, and many other
applications.
For
low voltage applications, the following controllers maintain up to 3.3MIPS down
to 2.7 volts.
The
AT89C51CC02 with 16Kbytes Flash and 0.5Kbytes RAM + a simple 4 message objects
CAN engine packaged into a Small Pin Count package is excellent for low end
applications where a minimum DeviceNet or CANopen slave stacks are used. It is
an ideal low cost product for a CAN controller push-button.
The
AT89C51CC01 features 32Kbytes Flash and 1.2 Kbytes RAM, and is well-positioned
for slave applications. It offers 2 Kbytes of Boot flash, with at least 3 MIPS
remaining for the application on top of a CANopen or DeviceNet stack. The chip
features an 8 channel 10 bit A/D converter, 3 timers, a 5-channel high speed
input/output timer units, and 32 I/Os. Its 15 message objects and the 1.2Kbytes
RAM make the chip suitable for complex I/O systems.
The
AT89C51CC03 provides 64Kbytes Flash for application programs and 2Kbytes RAM
for a larger object Dictionary. The built-in SPI port also assists
communication with other devices. It features 15 message objects as well as
2Kbytes Bootloader and 2Kbytes EEPROM.
USB MCU'S
Built
for today's increasingly connected applications, Atmel 8051 USB
microcontrollers offer powerful interface options that are ideal for devices
like Flash recorders, cameras, and cell phones. The AT89C5131A, a popular
device in this series, offers an efficient combination of features and
performance. It combines 32K bytes of Flash memory, 1.2K bytes RAM, 1K EEPROM,
7 USB Endpoints, TWI, SPI, UART, and Programmable Counter Array (PCA).
The
AT89C5132 is a mass storage device controlling data exchange between various
Flash modules, HDD and CD-ROM. It includes 64K Bytes of Flash memory and allows
In-System Programming through an embedded 4K Bytes of Boot Flash Memory.
This
versatile device provides all the necessary features for man-machine interface
including, timers, keyboard port, serial or parallel interface (USB, SPI, IDE),
ADC input, I2S output, and all external memory interface (NAND or NOR Flash,
SmartMedia, MultiMedia, and DataFlash cards).
LIGHTING MCU'S
Optimized
for lighting control applications, the Atmel AT83EB5114 is a high performance
version of the 80C51 8-bit microcontroller in a low pin count package. It has
all the features of the standard 80C51 with 4 Kbytes program memory, 256 bytes
of internal RAM, a 7-source, 4-level interrupt system, an on-chip oscillator,
and two timers/counters. The AT83EB5114 includes a serial two-wire interface
EEPROM housed together with the microcontroller die in the same package.
ROMLESS
Atmel
offers a powerful ROMless 8051 microcontroller suitable for existing ROMless
applications that require a combination of performance, flexibility, and power
efficiency. The AT80C51RD2 microcontroller retains all features of the Atmel
80C52, with 256 bytes of internal RAM, a 7- source 4-level interrupt
controller, and three timer/counters.
To
enhance system performance, this ROMless microcontroller features a
programmable counter array, an XRAM of 1024 bytes, a hardware watchdog timer,
and a keyboard interface. It also includes a versatile serial channel that
facilitates multiprocessor communication (EUART), and a speed improvement
mechanism (X2 mode).
