  1. F-RAM Solution for Smart E-Meters Replace EEPROMs with a Superior Solution Presentation: To provide an engineering overview to customers for a Cypress solution. Title slide: To define what the presentation will cover. The subtitle is a one-sentence statement of the key opportunity.

  2. E-Meters Are Getting Smarter • 33 million Smart E-Meters will be producedthis year, with a 20.7% • CAGR through 2017 • Electric utilities are demanding more smart functionality from E-Meters • Time-of-day usage tracking • Power quality monitoring • Real-time communication • Tamper-detection sensors and alarms • This functionality requires new components–including additional • nonvolatile memory–resulting in higher BOM cost and power consumption • Smart E-Meter BOM cost and power consumption are key design parameters • High demand for Smart E-Meters has increased competition • Utilities demand low-power Smart E-Meters to meet regional regulatory requirements • You require low-cost and low-power nonvolatile memory solutions Smart E-Meter By Landis + Gyr Market Vision: To define the market opportunity. Presents compelling data and end product photos relevant to the local market. 3

  3. Terms You Will Hear Today • Smart E-Meter • An advanced electric meter that time-stamps and records consumption and device diagnostic data and automatically communicates it to a utility company • Electrically Erasable Programmable Read-Only Memory (EEPROM) • A common nonvolatile memory that uses floating-gate technology to store data • Soak Time • The 5 ms required to complete an EEPROM Page Write after the data is presented at the input buffers • Write On Power Loss • A failsafe method in which an MCU senses system power loss and instantly performs a Page Write of critical data to nonvolatile memory • Write Endurance • The number of times a nonvolatile memory cell can be rewritten before it wears out • Wear Leveling • A method to prolong EEPROM Write Endurance that uses an EEPROM with up to 8x excess capacity and a software algorithm to move storage to unused memory addresses before the Write Endurance limit on an active address is reached • Ferroelectric Random Access Memory (F-RAM)™ • A fast-write, high-endurance, low-power nonvolatile memory that uses ferroelectric technology to store data Terms of Art (ToAs): To clearly define for engineers all ToAs used in the presentation.To carefully and fully define Cypress-proprietary ToAs needed to explain our system solution. 4

  4. Design Problems Engineers Face • 1. Smart E-Meters must log all energy consumption and diagnostic data • Smart E-Meter EEPROMs require 5 ms of active power per Page Write for Soak Time • Soak Time requires additional capacitors or batteries to perform a Page Write On Power Loss • 2. Typical Smart E-Meter applications exceed the 1 million write-cycle limitation of EEPROM • Wear Leveling is required to improve the Write Endurance of EEPROM over a Smart E-Meter’s 15-year lifespan • Wear Leveling requires up to 8x the memory density and additional software, increasing cost • 3. Utility companies prefer Smart E-Meters with low power budgets • Many utility companies specify a maximum 1-W consumption for a Smart E-Meter • Eliminating Soak Time provides you with a larger power budget for other components • F-RAM solves these problems • Requires no Soak Time,enabling fast write • Requires no additional capacitors or batteries • Provides 100 trillion write cycles (200x the lifespan of a typical Smart E-Meter) • Consumes 2x to 5x less active power than EEPROM • F-RAM offers you an opportunity to replace EEPROMs with a superior solution Traditional Approach and Challenges: To present the traditional approach and the challenges engineers will face when using it to realize the Market Vision. Ends with a one-sentence segue clearly stating the benefit of the Cypress solution. 5
