RISC Microprocessor Multichip Package

OVERVIEW

The WEDC 755/SSRAM multichip package is targeted for

high performance, space sensitive, low power systems and

supports the following power management features: doze,

nap, sleep and dynamic power management.

The WED3C7558M-XBX multichip package consists of:

755 RISC processor

Dedicated 1MB SSRAM L2 cache, conﬁgured as

128Kx72

21mmx25mm, 255 Ceramic Ball Grid Array (CBGA)

Core Frequency/L2 Cache Frequency (300MHz/

150MHz, 350MHz/175MHz)

Maximum 60x Bus frequency = 66MHz

The WED3C7558M-XBX is offered in Commercial (0°C

to +70°C), industrial (-40°C to +85°C) and military (-55°C

to +125°C) temperature ranges and is well suited for

embedded applications such as missiles, aerospace,

ﬂight computers, ﬁre control systems and rugged critical

systems.
