Overview
The Zylogic ZE5 configurable system-on-chip inte-
grates, on a single device, a performance-
enhanced 8032 “Turbo” embedded microcontroller,
a large block of SRAM, a high-speed dedicated
system bus, and configurable logic, intimately con-
nected to the processor and system bus. The ZE5
family is a highly integrated, fully static single-chip
system optimized for embedded systems applica-
tions. Each member of the ZE5 family contains an
identical microcontroller and set of dedicated re-
sources, as shown in Figure 1. However, the size
of the dedicated system RAM, the number of pro-
grammable I/O (PIO) pins, and the amount of con-
figurable system logic grows with the larger mem-
bers of the family, as shown in Table 1.
The embedded high-performance 8032-based
"Turbo" microcontroller is instruction-compatible
with other industry-standard 8032/52-based de-
vices, leveraging the vast software library for the
8032 architecture. While the instruction cycle for
the original 8032 microcontroller is 12 clock cycles,
the 8032 "Turbo" microcontroller provides better
performance because each instruction cycle is
only four clock cycles. The result is improved per-
formance at the same clock frequency.
The 8032 "Turbo" core offers other advantages
over the original 8032. The 8032 "Turbo" MCU
provides a protected watchdog timer plus an addi-
tional data pointer, easing data transfer routines.
