Combo-Key`applications`that`combine`remote`keyless`entry` with`vehicle`immobilization The`NXP`NCF2960`is`a`second-generation`Combo-key`solution` that`combines`a`transponder,`a`microcontroller,`and`a`radio` transmitter`in`a`tiny`(4`x`4`mm)`footprint.`
The`basic`transponder`operation`is`compatible`with`NXP’s` security`transponder`families,`including`HT3,`HT-AES,`and`` HT-Pro2.`Custom`transponder`functions`can`be`implemented` using`the`ROM`library`of`the`device`by`the`application. The`transponder`circuitry`is`powered`from`the`LF`field`and` does`not`require`a`device`battery`supply.`As`a`result,`full` operation`is`possible`even`when`the`battery`is`low.` The`RISC`controller`uses`NXP’s`third-generation`Micro`RISC` Kernel`(MRK`III),`a`low-power`implementation`that`features` a`16-bit`architecture`and`executes`instructions`in`a`single
The`on-chip`UHF`transmitter`requires`only`a`single`27.6`MHz` reference`crystal`and`loop`antenna`matching`circuitry`to`operate` in`one`of`the`following`bandwidths:``315`/`434`/`868`/`915`MHz` bands.`The`RF`multi-channel`capability`enables`frequency` hopping`and`ensures`reliable`operation`in`RF-jammed`environments. There`are`up`to`eight`I/O`ports,`with`one`designed`for`use`with`a` dedicated`LED`driver`port,`and`up`to`eight`inputs`for`command` buttons.`There`is`a`temperature`sensor`for`battery`management` and`an`on-chip`pseudo-random`number`(PRN)`generator`for`use` with`security`protocols.` A`fractional-N`PLL`allows`compensation`for`initial`XTL`tolerance.` The`device`includes`2`KB`of`ultra-low-power`serial`EEPROM` memory`(with`access`control`defined`by`the`application),`1`KB`` of`RAM,`and`up`to`16`KB`of`Flash-like`EROM`for`the`application` code.`The`keyless`entry`code`can`be`generated`by`the`built-in,` hardwired`calculation`unit`or`by`a`software-based`algorithm.` The`device`is`housed`in`a`tiny`24-pin`HVQVN`package`that` consumes`only`16`mm2`of`board`space,`so`it`enables`ultracompact`designs`with`maximum`freedom`for`key`styling.` Wettable`package`flanks`allow`optical`soldering`inspection` without`an`x-ray. The`Flash-like`EROM`of`the`device`supports`in-circuitry` programming`and`debugging`of`the`application`code.` machine`clock`cycle.
