Hyperstone RISC/DSP
Various types
The Hyperstone E1-32X RISC/DSP family is available in various types. The external data bus-width is 32 bit and 16 bit for the E1-32X and E1-16X series, respectively. The package types for the E1-32X series are 144-pin TQFP (20x20x1.4mm) whereas the E1-16X series comes in a very compact (14x14x1.4mm) 100-pin TQFP package. Each type has 16 kByte on-chip RAM and maximum clock rates of 120 MHz unb 0.25 µm
