CY8C21x34 Final Data Sheet  
PSoC® Overview  
CPU core, called the M8C, is a powerful processor with speeds  
up to 24 MHz. The M8C is a four MIPS 8-bit Harvard architec-  
ture microprocessor.

System Resources provide additional capability, such as digital  
clocks to increase the flexibility of the PSoC mixed-signal  
arrays, I2C functionality for implementing an I2C master, slave,  
MultiMaster, an internal voltage reference that provides an  
absolute value of 1.3V to a number of PSoC subsystems, a  
switch mode pump (SMP) that generates normal operating volt-  
ages off a single battery cell, and various system resets sup-  
ported by the M8C.

DIGITAL SYSTEM  
DigitalPSoCBlockArray  
Row 0  
The Digital System is composed of an array of digital PSoC  
blocks, which can be configured into any number of digital  
peripherals. The digital blocks can be connected to the GPIO  
through a series of global buses that can route any signal to any  
pin. Freeing designs from the constraints of a fixed peripheral  
controller.

The Analog System is composed of four analog PSoC blocks,  
supporting comparators and analog-to-digital conversion up to  
8 bits in precision.

The Digital System  
The Digital System is composed of 4 digital PSoC blocks. Each  
block is an 8-bit resource that can be used alone or combined  
with other blocks to form 8, 16, 24, and 32-bit peripherals, which  
are called user module references. Digital peripheral configura-  
tions include those listed below.  
The Analog System  
The Analog System is composed of 4 configurable blocks,  
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 common PSoC  
analog functions for this device (most available as user mod-  
ules) are listed below.  
PWMs (8 to 32 bit)  
PWMs with Dead band (8 to 32 bit)  
Counters (8 to 32 bit)  
Analog-to-digital converters (single or dual, with 8-bit resolu-  
Timers (8 to 32 bit)  
tion)  
UART 8 bit with selectable parity  
SPI master and slave  
Pin-to-pin comparator  
Single-ended comparators (up to 2) with absolute (1.3V) ref-  
erence or 8-bit DAC reference  
I2C slave and multi-master  
Cyclical Redundancy Checker/Generator (8 to 32 bit)  
IrDA  
1.3V reference (as a System Resource)  
In most PSoC devices, analog blocks are provided in columns  
of three, which includes one CT (Continuous Time) and two SC  
(Switched Capacitor) blocks. The CY8C21x34 devices provide  
limited functionality Type “E” analog blocks. Each column con-  
tains one CT Type E block and one SC Type E block. Refer to  
the PSoC Mixed-Signal Array Technical Reference Manual for  
detailed information on the CY8C21x34’s Type E analog blocks.  
Pseudo Random Sequence Generators (8 to 32 bit)  
The digital blocks can be connected to any GPIO through a  
series of global buses that can route any signal to any pin. The  
buses also allow for signal multiplexing and for performing logic  
operations. This configurability frees your designs from the con-  
straints of a fixed peripheral controller.  
Digital blocks are provided in rows of four, where the number of  
blocks varies by PSoC device family. This allows you the opti-  
mum choice of system resources for your application. Family  
resources are shown in the table titled “PSoC Device Charac-  
teristics” on page 3.
