Compact architecture and high performance give
you a solid base for meeting or exceeding your
project requirements Hyperstone E1-32X/E1-16X
RISC/DSP
Compact design and low power consumption.
The Hyperstone's minimum transistor count results in
a low power consumption of about 80 mW at 50 MHz
(2.7 V) for the complete chip. An automatic power-
down reduces power consumption even further in
many applications. Due to the on-chip bus interface,
total power consumption depends on the external
load connected to the chip. The low power consumption
makes very small packages possible.
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 E1-16 series, respectively.
The package types for the E1-32X series are 144-pin
TQFP (20 x 20 x 1.4mm) and 160-pin PQFP
(28 x 28 x 3.4mm), whereas the E1-16X series comes
in a very compact (14 x 14 x 1.4mm) 100-pin TQFP
package. Each type has 8 kByte on-chip RAM and
maximum clock rates of up to 80 MHz.
