Mixed signal array controls vocal smoke
alarm
SignaOne Safety's latest intelligent smoke alarm with prerecorded messages to help in case of a fire is built around a mixed-signal programmable array
SignalOne Safety, a specialist in safety product technology, has built its award-winning Vocal Smoke Alarm around the PSoC mixed-signal array from Cypress Semiconductor The flexible, programmable PSoC chip controls critical detector functions such as sensing smoke levels and initiating a series of alarms to wake household members and guide them to safety

Nonvolatile SRAMs expand to 8Mbit
New 2 and 8Mbit nvSRAMs feature access times as low as 20ns, infinite read, write and recall cycles, and 20-year data retention.
Design tool bridges high and low levels
Integrated design environment includes both code-free and high-level-language programming modes in one package.
Children faced with an emergency are much more likely to respond to a familiar voice than to a traditional alarm, according to pediatric experts.
When it detects smoke, the SignalOne product alternates a siren tone with recorded messages including exit instructions.
In a patent-pending feature, the PSoC CY8C24423A device measures voice recording levels to ensure sufficient volume at playback.

Programmable radio chip runs wireless mice
A microdongle that is roughly the size of a US dime uses the fully integrated CYRF69213 PRoC LP device to deliver low-power wireless connectivity to Darfon's mice.
PSoC also monitors system power and initiates a warning light when the batteries need to be replaced.
It prolongs battery life by initiating a sleep mode at regular 30s intervals.
"SignalOne Safety is committed to delivering innovative products that improve home safety, and the ease-of-use and flexibility of the PSoC solution supported the various dynamic feature requirements of our Vocal Smoke Alarm", says Bruce Black, Chairman and CFO of SignalOne Safety.
"PSoC delivered customisable performance, integration, and reduced design time and BOM cost".
"Having SignalOne Safety select Cypress for its Vocal Smoke Alarm speaks volumes about the reliability and flexibility of our PSoC devices", says Scott Harmel, Vice President of Marketing for Cypress's Consumer and Computation Division.
"PSoC's unique architecture is an excellent match for applications that require monitoring and control of multiple, critical functions".
PSoC devices employ a highly configurable system-on-chip architecture for embedded control design, offering a Flash-based equivalent of a field-programmable ASIC without lead-time or NRE penalties.
PSoC devices integrate configurable analogue and digital circuits, controlled by an on-chip microcontroller, providing both enhanced design revision capability and component count savings.
They include up to 32Kbyte of Flash memory, 2Kbyte of SRAM, an 8x8 multiplier with 32bit accumulator, power and sleep monitoring circuits, and hardware I2C communications.
The flexible PSoC resources allow designers to future-proof their products by enabling firmware-based changes during design, validation, production, and in the field.
The unique PSoC flexibility shortens design cycle time and allows for late-breaking feature enhancements.
All PSoC devices are also dynamically reconfigurable, enabling designers to morph internal resources on-the-fly, utilizing fewer components to perform a given task.
Easy to use development tools, including one-of-a-kind PSoC ExpressT Visual Embedded design tool, let developers design at the application level, with no C or assembly coding.
With access to dozens of tested and verified device drivers, a design can be completed in hours or days instead of weeks or months.
The PSoC family's analogue features include rail-to-rail inputs, programmable gain amplifiers and up to 14bit ADCs with exceptionally low noise, input leakage and voltage offset.
A single PSoC device can integrate as many as 100 peripheral functions saving customers design time, board space and power consumption while improving system quality.
Customers can save from US $.05 to as much as $10 in system costs.
