"The FM3130 has been optimized for price-sensitive applications," explains Mike Alwais, vice president of Marketing at Ramtron. "This FRAM-Enhanced Processor Companion has been well-received in consumer-centric markets in Asia and was developed to support a number of specific customer design-ins that are already in place, including HDTVs and printers."
About the FM3130
The FM3130 combines 64Kb of FRAM with a real-time clock/calendar (RTC) that incorporates an alarm and a programmable frequency clock output, and uses a common 12pF watch crystal. The alarm compares user-programmed alarm values to corresponding RTC time/date values, creating an ideal solution for automatic on/off, channel switch and parental control and personal video recorder (PVR) functions in high-end televisions.
An industry-standard 2-wire bus is used to access the memory and to control the RTC. Available in an 8-pin DFN (dual flat no-lead) package that is footprint-compatible with TSSOP8s, or a standard 8-pin, 150-mil SOIC package, the device operates from 2.7 to 3.6 volts over the entire industrial temperature range (-40 degrees C to +85 degrees C).
FM3130 Features:
-- 8Kx8 FRAM -- 64 kilobits of true nonvolatile RAM (not battery packed).
FRAM memory technology replaces system SRAM or nonvolatile memory since it
reads and writes at bus speed with NoDelay™ writes, 10 year data
retention and unlimited read/write endurance.
-- Real-Time Clock (RTC) Operation -- A timekeeping device that can be
battery- or capacitor-backed for permanently powered operation. It offers
a software calibration feature for high accuracy, an alarm and a
programmable frequency clock output.
-- Backup Power -- The real-time clock/calendar is intended to be
permanently powered. When the primary system power fails, the voltage on
the VDD pin will drop. When VDD is less then 2.5V, the RTC (and event
counters) will switch to the backup power supply on VBAK. The backup
source can be either a battery or capacitor.
-- Trickle Charger -- Facilitates capacitor backup. The VBAK pin can
optionally provide a trickle charge current. Data is nonvolatile so it
won't be lost if the capacitor fails.
About the Processor Companion
The Processor Companion is a highly integrated FRAM-enhanced system management solution that supports virtually any microcontroller- or microprocessor-based design. By integrating nonvolatile FRAM, individual system features are improved compared with discrete versions, creating a single-chip solution with superior bill-of-material cost and reduced board space.
Pricing and Availability
Samples of the FM3130 are currently available in an 8-pin SOIC package, with pricing starting at $2.20 in 10K quantities.
About Ramtron
Ramtron International Corporation, headquartered in Colorado Springs, Colorado, is a fabless semiconductor company that designs, develops and markets specialized semiconductor memory, microcontroller and integrated semiconductor solutions used in a wide range of product applications and markets worldwide. Ramtron pioneered the integration of ferroelectric materials into semiconductor products, which enabled the development of a new class of nonvolatile memory products called ferroelectric random access memory (FRAM) products. FRAM products merge the advantages of multiple memory technologies into a single device that retains information without a power source, can read and write at high speeds, can be written to many times, and consumes low amounts of power. Additionally, Ramtron works with various leading-edge licensees and manufacturers to bring its technology to market. For more product information, visit www.ramtron.com.
