The eCOG1 family is targeted at TCP/IP network, RTOS and other communication system. 16-bit RISC Harvard architecture and the flexible multiplexed clocking architecture make it very low power consumption and practical for battery-powered instruments and devices. Many advanced features are included such as DMA, host and memory interfaces and modular system interfaces and multiple UARTs (up to 4 UARTs).

Current Applications and Major Growth Markets for Embedded Communication

• TCP/IP network application. *
• RTOS, such as PicOS and ChronOS.
• Communication system using multiple UARTs.**

Easy-to-use, free software tools are available from Cyan including automatic peripheral configuration and full ANSI C Compiler with unlimited use.
  

Core

• Architecture
• 25MHz 16-bit RISC Harvard architecture, with External Host Interface (EMI) supporting both memory mapped and DMA transfers between an external host processor and eCOG1 internal SRAM.
• Memory Management Unit (MMU) enables up to 32MB internal and external (via. External Memory Interface (EMI)) mixed memory addressing.
• 29 GPIO pins fully configurable.
• 81 pin LFBGA and 128 pin LQFP packages.


• Internal Memory
• 64KB Flash organized as 32K x 16 bits. Eight blocks with individual blocks read or write protected. 256 Byte erase block size. Typically 200K write/erase cycles.
• 4KB SRAM plus 2KB Cache.
• 100 years data retention.

Peripheral

eCOG1 port configuration and individual on-chip peripherals can be set up by the convenient and graphical tool, “The Peripheral Configuration Editor” in CyanIDE without writing code. Can use same chip for several designs.

• Communications
• 2 x UART and 2 x USART serial ports with automatic parity generation and detection.
• DUSART’s protocol engines,
• Standard UART
• SPI Interface supporting both master and slave roles.
• I2C multi-master, multi-drop 2 wire bus.
• Smart Card Interface ISO 7816 compliant.
• IR/IrDA function. Compatible with common ASK, PM, PPM modulation schemes.
• Generic User Serial Port (USR)


• General
• 12 bit A/D Converter with On chip Temperature sensor and Vdd Sensor.
• 8 Timers including
• 16 bit watchdog,
• 16 bit clock timer,
• 24 bit long interval timer,
• 2 x 16 bit general purpose timers/event counters,
• 1 x 16 bit timer providing multiple event capture registers.
