CY8C24894 The PSoC family consists of many Programmable System-on-Chip with on-chip controller devices. All PSoC family devices are designed to replace traditional microcontroller units (MCUs), system ICs, and the numerous discrete components that surround them. Configurable analog, digital, and interconnect circuitry enable a high level of integration in a host of industrial, consumer, and communication applications. The Digital System The digital system is composed of four digital PSoC blocks.
CY8C24894 Figure 2. Analog System Block Diagram The analog system is composed of six configurable blocks, each comprised of an opamp circuit allowing the creation of complex analog signal flows. Analog peripherals are very flexible and can be customized to support specific application requirements. Some of the more common PSoC analog functions (most available as user modules) are listed below.
CY8C24894 Additional System Resources System resources provide additional capability useful for complete systems. Additional resources include a multiplier, decimator, LVD, and power-on reset (POR). Brief statements describing the merits of each resource follow. ■ ■ Digital clock dividers provide three customizable clock frequencies for use in applications. The clocks can be routed to both the digital and analog systems. Additional clocks are generated using digital PSoC blocks as clock dividers.

CY8C24894 Document Conventions Units of Measure The following table lists the units of measure that are used in this document. Table 34.
CY8C24894 Glossary (continued) bias 1. A systematic deviation of a value from a reference value. 2. The amount by which the average of a set of values departs from a reference value. 3. The electrical, mechanical, magnetic, or other force (field) applied to a device to establish a reference level to operate the device. block 1. A functional unit that performs a single function, such as an oscillator. 2.
CY8C24894 Glossary (continued) duty cycle The relationship of a clock period high time to its low time, expressed as a percent. emulator Duplicates (provides an emulation of) the functions of one system with a different system, so that the second system appears to behave like the first system. external reset (XRES) An active high signal that is driven into the PSoC device. It causes all operation of the CPU and blocks to stop and return to a pre-defined state.
CY8C24894 Glossary (continued) microcontroller An integrated circuit chip that is designed primarily for control systems and products. In addition to a CPU, a microcontroller typically includes memory, timing circuits, and I/O circuitry. The reason for this is to permit the realization of a controller with a minimal quantity of chips, thus achieving maximal possible miniaturization. This in turn, reduces the volume and the cost of the controller.
CY8C24894 Glossary (continued) shift register A memory storage device that sequentially shifts a word either left or right to output a stream of serial data. slave device A device that allows another device to control the timing for data exchanges between two devices. Or when devices are cascaded in width, the slave device is the one that allows another device to control the timing of data exchanges between the cascaded devices and an external interface.

CY8C24894 ■ WORKAROUND To prevent an invalid Flash read, a dummy read from each Flash page must occur before use of the pages. A delay of 5 µs must occur after the dummy read and before a real read. The dummy reads occurs as soon as possible and must be located in Flash page 0 before a read from any other Flash page. An example for reading a byte of memory from each Flash page is listed below. Placed it in boot.tpl and boot.asm immediately after the ‘start:’ label.
