Notes 1. Set the flash operation mode by using CMODE1 and CMODE0 bits of the option byte (000C2H/010C2H).
2. When using these oscillators, contact KYOCERA Corporation (http://global.kyocera.com/).
3. When using these oscillators, contact Nihon Dempa Kogyo Co., Ltd. (http://www.ndk.com/en/index.html).
4. This resonator can operate at up to 85°C. For details about the products that can operate at up to 105C,
contact the manufacturer of the resonator.
Remark Relationship between operation voltage width, operation frequency of CPU and operation mode is as below.
HS (High speed main) mode: 2.7 V ≤ V
DD ≤ 3.6 V@1 MHz to 32 MHz (When X1 oscillation: 1 MHz to 20 MHz)
2.4 V ≤ V
DD ≤ 3.6 V@1 MHz to 16 MHz
LS (Low speed main) mode: 1.8 V ≤ VDD ≤ 3.6 V@1 MHz to 8 MHz
LV (Low voltage main) mode: 1.6 V ≤ V
DD ≤ 3.6 V@1 MHz to 4 MHz
