Parameters above are transcribed from the manufacturer datasheet for reference only. Confirm the current datasheet revision and your application conditions before design-in.
Note: Important correction to the assumed spec: this OPN is the 1.2 GHz, 621-ball 21x21 mm, 0 to 105 °C, low-power version with security disabled (NXP description: 'Quad-core, 1.2GHz, 0 to 105C, Security disabled, 21x21 pkg, Low power'). The 1.6 GHz / 780-ball 23x23 mm / SEC-enabled version is a different ordering code (e.g. LS1043ASE8QQB). OPN 935338898557, active status, tray/bakeable packaging.
