4 / 406 page TX1942CY/CZ TMP1942CY/CZ-3 (14) Interrupt sources • 4 CPU interrupts: software interrupt instruction • 45 internal interrupts: 7 priority levels, with the exception of the watchdog timer interrupt • 29 external interrupts: 7 priority levels, with the exception of the NMI interrupt The external sources include 14 KWUP sources, which are all assigned to a single interrupt vector, and 4 extended interrupts (INTB, INTC, INTD, and INTE), which are all assigned to a single interrupt vector with an identification flag. Thus, the actual number of external interrupt sources is 13. (15) 108 pin input/output ports (16) Three standby function • IDLE, SLEEP, and STOP (17) Dual clocks • RTC clock: Low-speed clock (32.768 kHz) (18) Clock generator • On-chip PLL (x4) • Clock gear: Divides the operating speed of the CPU by 1/2, 1/4 or 1/8 (19) Operating voltage range: 2.7 to 3.6 V PC and PF are 2.7 to 3.6 V or 4.5 to 5.25 V for 5 V-enabled ports. (20) Operating frequency • 32 MHz (Vcc ≥ 3.0 V) • 28 MHz (Vcc ≥ 2.7 V) (21) Package • 144-pin QFP (16 x 16 x 1.4 (t) mm, 0.4-mm pitch): FDUE/CZUE/CYUE • 177-pin CSP (13 x 13 x 1.4 (t) mm, 0.8-mm pitch): FDXBG/CZXBG Note: TMP1942FDXBG (Package: 177-pin CSP) is under development. |
