The device also supports a connection to a network controller through a reduced media-independent interface RMII , which can be configured as a network controller-sideband interface NC-SI . The MAX72420, along with a minimum number of additional components, can be configured to support all management functions, while retaining the flexibility to support a significantly expanded system through various peripheral interfaces. Because management functions typically require a limited amount of bandwidth and occur relatively infrequently, an embedded RISC engine operating over an SPI memory interface with zero-wait-state internal SRAM for critical code execution provides optimal performance with a low system cost. The MAX72420 also supports the next generation of SPI devices, which can double or quadruple the interface bandwidth by using additional signal pins. Several peripheral functions are included in the device to support a variety of embedded controller requirements. External component requirements are limited to a single SPI flash memory device and peripherals dedicated to system management functions. Additional peripherals can be added through the GPIO interface. The MAX72420 is available in an 88-ball, chip-scale ball-grid array CSBGA package.

Overview

The MAX72420 is a highly integrated management device intended to provide a costeffective solution for baseboard, storage, or embedded system management. The device contains a high-performance, 32-bit RISC engine a 10/100 Ethernet media-access controller MAC four master/slave mode interfaces a high-speed master/slave core two general-purpose universal asynchronous receiver-transmitters UARTs three 32-bit timers up to 54 bits of general-purpose input/output GPIO 64KB of high-speed SRAM an SPI memory interface and an EJTAG port for firmware debug and development. The device optionally supports a configurable low-pin-count LPC system interface for applications requiring a direct system connection. The device also supports a connection to a network controller through a reduced media-independent interface RMII , which can be configured as a network controller-sideband interface NC-SI . The MAX72420, along with a minimum number of additional components, can be configured to support all management functions, while retaining the flexibility to support a significantly expanded system through various peripheral interfaces.

Because management functions typically require a limited amount of bandwidth and occur relatively infrequently, an embedded RISC engine operating over an SPI memory interface with zero-wait-state internal SRAM for critical code execution provides optimal performance with a low system cost. The MAX72420 also supports the next generation of

SPI devices, which can double or quadruple the interface bandwidth by using additional signal pins. Several peripheral functions are included in the device to support a variety of embedded controller requirements. External component requirements are limited to a single SPI flash memory device and peripherals dedicated to system management functions. Additional peripherals can be added through the GPIO interface.

The MAX72420 is available in an 88-ball, chip-scale ball-grid array CSBGA package.
