SC-605
Data sheet
The data memory is internal static RAM. The RAM is configured in 640 17-bit words. All memories are designed
to consume minimum power at a given system clock and algorithm acquisition frequency.
A flexible clock generation system enables the software to control the clock over a wide frequency range. The
implementation uses a phase-locked loop (PLL) circuit that drives the processor clock at a selectable frequency
between the minimum and maximum achievable. Selectable frequencies for the processor clock are spaced
apart in 65.536 kHz steps. The PLL clock-reference is also selectable; either a resistor-trimmed oscillator or a
crystal-referenced oscillator may be used. Internal and external clock sources are controlled separately to
provide different levels of power management.
The periphery consists of five 8-bit wide general-purpose I/O ports, one 8-bit wide dedicated input port, and one
16-bit wide dedicated output port. The bidirectional I/O can be configured under software control as either high-
impedance inputs or as totem-pole outputs. They are controlled via addressable I/O registers. The input-only
port has a programmable pullup option (70k
minimum resistance) and a dedicated service interrupt. These
features make the input port especially useful as a key-scan interface.
A simple one-bit comparator is also included in the periphery. The comparator is enabled by a control register,
and its pin access is shared with two pins in one of the general-purpose I/O ports. Rounding out the SC-605
periphery is a built-in pulse-density-modulated DAC (digital-to-analog converter) with direct speaker-drive
capability. The functional block diagram gives an overview of the SC-605 functionality.
